That said, .RS/.RE can be nested, while .TP, .IP, and .HP cannot,
which can be understood because the latter do not have explicit
closing macros.  If they could nest, how would you ever get out
of the indented item body again?

Note that in contrast to man(7), mdoc(7) does not have such a
restriction.  The .Bl macro freely nests, except that .Bl -column
cannot contain inner lists.

If you are forced to remain with man(7), it may be an option to
use .RS/.RE for the outer level, similar to this:

  top level text
  non-nesting tag
  body for the non-nesting tag
  outer tag
  outer body
  inner tag
  inner body
  back to outer body
  back to top level

Yes, i do admit that is ugly, but man(7) is almost never elegant
and definitely never semantic but always purely presentational.
At least the above is pure man(7) without resorting to low-level
roff requests like .in, and it works as you want, IIUC.
