In subversion, it's a builtin feature of subversion (svn:eol-style);
subversion will automatically convert all files correctly (if
svn:eol-style is specified correctly, which it is, for most of the
files).

In Mercurial, it's just a hook, and optional. So we can't be sure all
users use it correctly - and in my (limited) experience with Mercurial,
chances are high that users will make mistakes in that respect (i.e.
in one out of one cross-platform projects, a committer had issues
with CRLF, leading to catastrophic repository corruption).

So I think it's absolutely necessary that files with incorrect
eol-style are blocked from being pushed. Or else we will all
suffer and eventually die :-)
