This is a straw-man, since nothing stops people from running 8.0.0 even if the
replacement come in 8.0.1

Some people get scared of changes between even minor revision releases even
when we tell them it is safe to do. (Of course pushing a change like ARC out
in a minor release isn't going to help do away with that perception) Sticking
to a two-month/no-initdb cycle, I don't think we'll have to worry about
"piles-of-changes" that make things incompatible.

Especially when it doesn't even effect everyone involved. Or anyone... who
knows, maybe oracle is out submitting prior art and the thing never even gets
granted.
