First, I would say that a variant name should not include a hyphen.
That's problematic. Use an underscore if you want to separate words.
Then, I would say that you should have either an +rtf variant, or a
+no_rtf variant, but never both. (What would it do if you did not
specify any variant?)
I have never used the variants.conf file so I have no comment on that
feature. Well, maybe I do: the comment would be that variants vary
from port to port, so I can't see any usefulness in a global way to
specify variants that should be used for all ports.

I don't know about that.
