I'm not sure, Henrik will make that decision. Though there is no bug
reason for it to happen in 2.7.

Not that Henrik is aware of. Thus the RFC.
We just need it to be tested on all installs so we don't change defaults
behind people backs, and rip the code out of 3.2 then find its needed by
someone later who was on 2.x today.

Noted. Thank you.
That may just be the very reason for keeping it coded, but in off state
by default.
