In my mind, this was to stop having features enabled per pmd (and stop
the nightmare with 10 options in a pmd).
Having features globally enabled for all or nothing is still
acceptable, is it not ?

As a general rule, I prefer enabling only the things I use, but I am
not against this ?
Can you confirm the performance impact is negligible, always having
this in the pmds ?
Thanks.
