Well, I was initially inclined to agree with that, but then I did a
test-compile, and that immediately notices that you never tested this
at all and that it's completely broken.
There's still uses of PG_error in fs/proc/page.c, and in
include/trace/events/mmflags.h, and neither of those two cases are
new. One is unchanged from 2009, and the other one has gone through a
few code movements and re-orgs but also goes back over a decade ago.
So clearly this needs to be in linux-next, and as such this very much
is "next merge window".
