Just a thought, but have you tried setting the INDEX location in the 
default_mail_env ?  I'm not certain, but I believe the subscriptions file is 
included in the INDEX set, and by setting its location elsewhere, you would 
prevent it from being inside the Maildir.  This would prevent ownership 
hijacking, AND let everyone have their own subscriptions.

I'm not certain of this, so either someone else can fill in the details, or you 
could check the source (and please report your findings:)

Of course, I'm assuming you've read the Wiki (it looks like you have...)
