Anyone, feel free. The nightmare part is done, so this could be a case
where a PR actually pays off in terms of being able to use the
feature. There's no need for any unnecessary masochism (should there
ever be?).

Such exceptions can of course more easily be made when the adoption of
a version is still small, and almost all users will never see X.Y.0 or
X.Y.1. The fraction of 3.6 users is probably super tiny right now, and
even those users are likely to eagerly update to bugfix releases. For
instance, are there any major (LTS?) linux distros that already come
with 3.6.0 or 3.6.1? Well OK, 3.6.2 may be too late for some.
