I think that's not true. K's TLS also supports name-based TLS domains
(the TLS domain can be selected by setting an AVP) and it also supports
the servername extension (multiple TLS domains use the same socket).
AFAIK these features are not available in ser.

IIRC the tlsops module is basically just the "select" ported from ser to
Kamailio. Of course the servername pseudo variable is not available in
Otherwise, if there is a generic mechanism to access "selects" via PV
then the tlsops could be removed (with servername added to select).
