You mean why doesn't it contain POP3? I guess mainly because that's how it was submitted to me and I didn't think of it. Also now that I do think about it, I'm still not sure if it should contain POP3 by default. Even Dovecot's on example-config doesn't enable POP3 by default.

I don't understand. If you want LMTP enabled, you also need to list its socket to dovecot.socket. LMTP is executed in a similar way to IMAP/POP3. (If you want LMTP via UNIX socket, I don't really know the answer to that. Does systemd support listening on UNIX sockets? Maybe it requires patching Dovecot more.)
