Thanks for the inputs! I'll write down the proposal then.

I agree with others that you should start with text on path. First,
because this is required SVG functionality that we miss
(spacing="auto"); second, because typically gaps in the text on path
are much worse than in plain text and would benefit more from an
automatic spacer; and thid, because this problem is more general, and
if you find a good solution for it, you will have no problem adapting
it for the simpler horizontal text case.

Those all are sound reasons, so ok, I agree, too.

I'm not sure it's possible to do this as an extension, though, because
this is core SVG functionality. But you can code a prototype in Python
and then port it into Inkscape with our help.

Yes, please. Any help would be mostly welcomed!
