Might be true for the Apache project, but there's just as many
projects where the opposite is true. We have some of those.

Since everybody's already abusing 'svn:externals', a wiser choice
would be to introduce a 'svn:internals' with the desired behaviour,
eg. one that updates the files like the users are expecting.

Another Good Thing (TM) that this would bring to the table would be
that 'svn cp' could have an option named '--pin-internals' that users
could use when tagging a project, so that shared files remain tagged
(instead of following HEAD ?!).
