I agree that a secure Linux box should effectively guard any plain text
passwords stored in the .subversion folder from being read in the wild and
if someone could, then you have bigger problems than simply having your
password stored as plain text.

But having said that, it's still an issue for me and it's not far enough
that passwords are simply base64 encoded. Better, but not nearly as good
as if they were encrypted.

One problem that comes to mind is the backing up of the home directory for
all users. Anyone with access to the tapes now has a list of passwords with
access to the subversion servers, and worse if that password is used against
an LDAP server for authentication.

I know that you have to trust the people you work with and that their should
be proper security over the backup tapes, but no system is perfect and
encrypted passwords would do much to minimize problems like this.

ps: Having said that... if you all still disagree, I'd still rather have
your patch go through for whatever that's worth ;)
