Would I have to add some code somewhere to process this? (I'm often
surprised to find that these just work via some generic magic, e.g. the
buildjob stuff etc, but I don't think so in this case?)

Perhaps in ts-hosts-allocate-Executive alongside the equiv handling?

I think this wouldn't work for standalone mode, would it?

Given "marilith" is the host name and not any sort of name which would
identify "similar" machines -- really?
