I don't know how difficult it would be to create such algorithm
descriptions automagically.

AFAIU there are some general python scripts to provide it in processing:
e.g.
python/plugins/processing/algs/grass7/Grass7AlgorithmProvider.py
No, this is the provider itself, not a tool to create the descriptions.
and there are a lot of txt files providing the module interface
e.g
python/plugins/processing/algs/grass7/description/r.out.png.txt
r.out.png
Export a GRASS raster map as a non-georeferenced PNG image
Raster (r.*)
QgsProcessingParameterRasterLayer|input|Input raster|None|False
QgsProcessingParameterNumber|compression|Compression level of PNG file (0 =
none, 1 = fastest, 9 = best)|QgsProcessingParameterNumber.Integer|6|True|0|9
and other files
My question was whether it would be possible to create these description
files more or less automagically.
I think the python scripts for more complex operations have to be
created manually.
IIUC (from rapid reading of the threads on the qgis-developer list),
Rashad's suggestion was to keep the *AlgorithmProvider code in the QGIS
code base, but to possibly move the creation of the description and
script files to a plugin managed outside QGIS core, possibly by the
respective external software teams.
