Ok, that makes a lot of sense.

True, but those examples are different. Each of those is an example of
something Subversion explicitly supports and allows, but which for some
installations may be undesirable (and, for others, perfectly ok). That
sort of site policy enforcement clearly belongs in hooks.

On the other hands "incorrect line endings" in svn:ignore is a new
Subversion notion; users don't particularly care one way or the other
and neither did Subversion before 1.6. So it's an internal restriction
rather than a site policy choice, as in the hook examples you gave.
Yes, as with the dump/filter/load, putting such a hook script in place
is a reasonable *workaround* for the lack of Subversion handling of this
issue. But only a workaround.
