Is using the command line fast than using the GUI for batch processing?

Hello, the current rawtherapee 5.4 does not even have command line options for batch processing pictures. In my opinion this is a serious regression.
With the previous version, the one that supported options
-o outputfile -p pp3file -Y -c rawfile
I almost never converted raw to jpg while running interactively rawtherapee: when I was finished editing a raw picture, I just quit rawtherapee, thus auto-saving a .pp3 file, and immediately started to edit the next picture. When I was done I started a script (I can share it if needed) that did all the conversions in background. A little time wasting for restarting rawtherapee in background every picture was immaterial.

Unfortunately this does not work any more with 5.4, which means a lot of time wasting until the conversion is done interactively from within rawtherapee. Please developers, restore the command line options!

All the best, and keep up the great work!
