There's no reason why new modules can't be added during a freeze. The
main point is not to change existing code in a way which might break
anything which depends upon it (otherwise you just add new bugs as
fast as you fix existing bugs).

Region problem? Is that a gis.m problem, or elsewhere?

i.points should be doable in Tcl/Tk, although you might want to
salvage the mathematical code from i.points and keep that in a C
helper module rather than re-writing it in Tcl/Tk. Apart from anything
else, it may be useful for non-interactive use.

AFAICT, the main obstacles are v.digit and NVIZ. v.digit needs a
decision on a suitable toolkit (probably either Qt or wxWidgets) and a
volunteer. NVIZ requires someone to update Togl to 1.7 and to
conditionalise the GLX-specific code in do_zoom.c.
