This isn't equivalent - it will cause a change in behaviour for anyone

Correct, but this is likely the only recipe in the greater ecosystem
which has this behaviour, so I'm not that bothered to be honest. :)

The only recipe? There are many recipes which set a default
PACKAGECONFIG with ?= and many which set it with ??=. Your change is
effectively switching the vim recipe from one approach to the other.
The fact that adding PACKAGECONFIG options from a .bbappend with +=
sometimes works OK and sometimes not is a source of confusion for new
users.

You are right that no one seems to care though...
