If you make sure to run update.php, it's very rare
for your wiki to
break, unless you've hacked things or not updated your extensions or
such. We're usually pretty careful to avoid significant regressions
when upgrading wikis that are using supported/sane configurations.
Can we make update.php ask the user if he wants to install the new extension?
It's a regression for people who already have math
working. What's
the advantage? We have an awful lot of marginal features in core.
When have we ever split a feature that we'd released in core into an
extension, when a significant number of people were using it? I don't
see the point. It's not like we're going to significantly reduce the
size of the tarball or anything.
Is there any place we could get usage statistics for the math feature?
I think the advantages for new installations justify inconveniencing
some existing users, especially if we can automate installation of the
new extension, but this discussion would be better with some data.
