Another option might be simply to say that if an app has used FP,
VMX or
VSX -once-, then it's likely to do it again and just keep re-enabling
it :-)
I'm serious here, do we know that many cases where these things are
used
seldomly once in a while ?
For FP, I believe many apps use it only sporadically. But for VMX
and VSX,
yeah, it might well be optimal to keep it enabled all the time. Someone
should do some profiling...
