But libmfx is not supported anymore by upstream, who's moving to oneVPL, aka mfx 2.0.

You can think this is a bad move from Intel to remove feature, but, de facto, they don't support libmfx anymore, the new features will come only on oneVPL and the new hardware will only be supported in oneVPL.

The patchset allows to support libmfx if people want, and have the old featureset.
But it also allows to support oneVPL (mfx 2.0) if people want.

As long as this is a user choice, I don't see why this shouldn't be merged;
knowing also that upstream tells us that they only support 2.0, with less features.
(This is the issue always with upgrades of external libraries, even worse when they are hardware linked)
