There are no "good" subscribers trying to send email direct to a remote port 25 from behind a NAT.
Users, like myself, running Linux on home computers and laptops; our local sendmail-equivalents will in fact attempt direct delivery to remote SMTP MX servers, and we generally move around enough that setting a smarthost is semi-impractical, at least on laptops.
OpenVPN, et al... nice for being able to not only relay via the home server, but also access SMB or even NFS shares and the like, which you'd also not want reachable from the outside.
