I've always thought that with compression and EQ, the first and most important thing is the venue and audience. That doesn't change much during a gig.
On second place comes the sort of music you play.
At least that's what I think. I haven't gigged, so I do not have experience in this field.

I think the problem might be twofold.
you can use both EQ and compression to adapt your Genos to a new environment.(gig setting)
But you can also use them to improve your general sound in certain genres.
Now people playing just one genre on a gig, might be happy with only general settings.
But home players that want every song they play sound as good as possible might want a setting/song
they could make a twofold setting allowing both global changes as well as performance memory.
Global changes would be absolute in nature
Performance memory changes would be more relative in nature.
Which means that you could change in steps up or down from the Global setting.
to me EQ and expression are more like mixing tools.
Master effects, added to the final mix of a track.
For example if you have a dynamically played guitar part, you can use compression to to make it less dynamic (and make the rest of your mix less loud)
and then use the volume slider of the guitar to put it more upfront.
thats why having Master compression as a Global effect does not make much sense to me.
