There at least ~2400 MX hosts with published TLSA records for SMTP serving over
100k domains and growing.  In addition to Postfix and Exim, vendors are starting
to implement DANE for SMTP.  Adoption is not surprisingly slow, but TLSA for SMTP
is certainly not "dead", and adoption will accelerate as more MTAs and service
providers add support.

If you're talking about TLSA for HTTPS, then indeed it is not likely to be used
at all soon...  Whether that's dead or just dormant is presently academic.
