I guessed that, but if that is the case, "more is the same binary"
is irrelevant. "more" behaves differently from "less" might be, but
what "less" does is much less important than "more needs this default
setting to work pleasantly", which is what is missing.
So I'd say
Allowing PAGER_ENV to be set at build-time allows us to move
pager-specific knowledge out of our build. This allows us to
set a better default for FreeBSD more(1), which misbehaves if
MORE environment variable is left empty $in_such_and_such_way,
by defaulting it to -R.
without even mentioning anything about "less" may be a more
understandable justification for a patch that sets MORE only on
FreeBSD.
