Wouldn't that be a violation of RFC3986?

http://tools.ietf.org/html/rfc3986#section-4.4

Are there pages in the wild relying on that behavior (i.e. has Apple
received a bug report for pages breaking in Safari? [1])

[1] Hmm, seems like there is such a bug report, with people
misunderstanding RFC3986 §4.4 and relying on such broken behaviors:
http://bugs.webkit.org/show_bug.cgi?id=7763
(for the first example, it's at
http://www.polytechnique.fr/eleves/login.php, there's a <base
href="http://www.polytechnique.fr/eleves/"> and <form action="">
expected to be POSTed to login.php)
