Do I understand this and another reply correctly, that it incorporates 
into the rcd binary the "service jails" functionality which I introduced 
into rcng (<service>_svcj="YES" and <service>_svcj_options), but it is 
not a fully functional containerization environment like docker or 
kubernetes or such?

If I understand this correctly: both thumbs up!

There is a way of per-instance services in the ports tree. One example 
is www/oauth2-proxy (simplest example without much dependencies). As it 
rcd backward compatible I don't worry about the existing ports tree. My 
point here is: Are you aware of it? And as I have not seen the syntax of 
your UCL, do you think it allows similar flexibility? I have similar 
per-instance template support in www/openhab (but this is more complex 
to setup in testing than the oauth2-proxy).

Bye,
Alexander.
