The reality is no one has deployed TXT record mechanism. Current
deployments for this for some major service providers can be seen here:

dig _caldavs._tcp.icloud.com srv
dig _caldavs._tcp.fastmail.com srv
They all support both caldavs and carddavs. None of them have matching
TXT records and I am pretty sure none of the client implementations look
for TXT either.
caldav SRV defines only one related TXT record:
path=<context path>
Many other SRVs do not define any TXT records.
