Hi Andreas,

It is already possible, at the service level, we now have separate
packages for the different services so you can actually install only
what you want.

See: https://github.com/qgis/QGIS/pull/37682

But I doubt that you will gain any speed: the part of the code that
decides what service is invoked is really fast compared to the rest of
the processing.

Another simple thing I was thinking about is to have a service
"badlist" or a "goodlist" where we list in an environment variable the
services that we want to be loaded (or not loaded)

Cheers
