Mail transport agent MTA switch to dma from sendmail in 14.0-RELEASE

As stated in the release notes for 14.0-RELEASE
(https://www.freebsd.org/releases/14.0R/relnotes/)
the default MTA will be switched to dma away from sendmail.

But it states also that "sendmail and its configuration remain available".
Seems that it can be changed back easily by using the mailer.conf file from
/usr/share/examples/sendmail/mailer.conf.

My question is how long will sendmail remain in the FreeBSD base
installation. Is there some kind of a timeline when it finally will be
removed from the OS?

Thanks and Regards
