My understanding was that we avoid recommending use of obsolete
libraries.  Both tls.el and starttls.el are obsolete in 27.1.

The alternative to removing them would be to update it to say they are
now obsolete, I guess?  Please let me know if that is preferred.

Thanks, I've fixed that in the attached patch.

Best regards,
Stefan Kangas
