No, the analogues would be "unidimensional", "bidimensional", and
"many-dimensional".  There difference is that you close up prefixes (which
are not words by themselves), but you hyphenate compounds of independent
words.

Once that feeling materializes into a real concern, we can still consider
action.  Maybe there will at some point be a need for these functions, but
maybe we will need a similar function with slightly different
functionality, or whatever.  Hard to tell as long as we're fantasizing.

Was there ever a vote to add them?

Sounds good.  My main concern is that people will have a clear view of
what's standard and recommended for which situation, so that support will
be easier and users won't be confronted with a long list of equivalent,
undifferentiated options.
