The isa-support package is just one approach to the overall problem of
selection of non-baseline instructions, there are several other ones:

In future, isa-support may provide a generic runtime solution too,
similar to what chromium does, but that needs someone to work on it.

It is worse than that; there are now chips where different cores of the
SoC provide different capabilities, so each time you run a program it
might not start if you start it on the wrong core.
