Well, I can't now think of why it wouldn't work :) At least as

If user can directly modify it, he could at least make Dovecot display
wrong data about the mails, hide mails or possibly cause a buffer
overflow.

Easiest would be to specify different index location so it won't follow
symlink to the shared directory, eg.:

default_mail_env = maildir:~/Maildir:INDEX=~/Maildir/indexes/
