This seems to me like you're solving the problem in the wrong way. You
should fix the clients, not force the server to support something that the
IETF clearly thinks is a bad idea.

In 2.2 cyrus you can have per-service configuration options. In 2.1 I
suppose you can use the -C option to imapd or sieve to cause it to read
If you wanted to play worse games, you could have the sieve clients
connect to a UNIX socket provided by sivtest, but I suspect this is more
complicated than you want, especially when the solution is "make the
clients do STARTTLS".

This is definately what you want to patch, not the server. The server is
already providing the needed functionality.
