Note: it wasn't when Glenn posted that.  See Bug#31457 "27.0.50; Move
starttls.el and tls.el to lisp/obsolete/".

Emacs does warn about requiring files from obsolete.  Users loading
tls.el will now get this in *Messages*:

    Package tls is obsolete!

It's not super visible though, opening a connection with tls.el produces
several other messages too, so it looks something like this:

    Opening TLS connection to ‘example.com’...
    Opening TLS connection with ‘gnutls-cli --x509cafile /etc/ssl/certs/ca-certificates.crt -p 443 example.com’...
    Package tls is obsolete!
    Opening TLS connection with ‘gnutls-cli --x509cafile /etc/ssl/certs/ca-certificates.crt -p 443 example.com’...done
    Opening TLS connection to ‘example.com’...done
