I hope a late comment on this topic is acceptable - I have only just now seen this discussion and want to add my thoughts.
in 2019, after evaluating possible alternatives to LightRoom - both proprietary and FOSS - I decided to move from dt, factoring in the amount of learning support available in the significant portfolio of tutorial-type offerings on YouTube and elsewhere.
This choice caused me to virtually ignore the capability/functionality of RawTherapee, until I looked at it again starting a few months ago. The more I read and watch about RT the more I realise that this is an impressive product, about which far too little is known or referenced on the web in general
However, My earlier qualitative observations of RawTherapee still stand, to a certain extent: there is just not the same level of tutorial material available in the web, especially though YouTube. Granted there is a large amount of YouTube material on dt which has been ‘created’ by people who should never have been allowed access to a camera, a microphone and OBS-Studio, on the basis of their demonstrated inability to make a public presentation suitable for any audience - defined or not.
On the other hand there is a huge range of material on how to use dt created by those who are subject matters experts, and who also understand the art and science of making a video - they don’t give the impression that either their studio is on fire or that there is a desperately urgent need to respond to the call of nature, completing what should be a 20 minute video in 30 seconds.
In contrast RawTherapee doesn’t ‘offer’ either of these scenarios. The largest single source of YouTube videos appears to come from one creator with a pronounced ‘style’, which some students of RT might find somewhat off-putting, irrespective of the educational value in these videos.
So it seems to me that a lot more video (and written) educational material is required to do justice to the product and the efforts of the developers. The apparent comparative weakness of the product in respect to its lack of DAM needs to be addressed by publishing articles which show, in practice, how RT can by connected with other FOSS products so as to address such needs.
In addition the product should be given greater publicity - for example a link to this very Pixls.us topic should appear in the ‘News’ section of the web-site - which appears to be a little ‘thin’ in comparison to all the development work that is going on.
In that regard, the details of ‘what has changed in this release’ reads too much like a list of development line items that a software development manager might have regular nightmares about, rather than an explanation of what the changes can actually do for a non-developer raw processor user to enhance the results of their image editing.
There should be a link in the web-site to this very software category on Pixls.us, so that potential new users can see the reach and range of support and product functionality that is available. Perhaps the question needs to be asked if there is anybody in the wider developer team - including those responsible for tasks other than code creation - who should be looking at the publicity needs of the project, or whether this task should even be considered in a FOSS development environment.

Hope it helps!
if it wasn’t for it I would have been far worse of but it is undeniable that it has a few areas in which it needs work. I also need to look into getting a newer version. If you can point to some good tutorials I’d appreciate it. My main issue with it is landscape panos where there are electrical lines 
I can send an example if you like. But yeah good to meet another Hugin user 
Well thank you very much,
