Unless there are no reference data/points (or in XY "projection"), I
tend to manipulate my data with GDAL before importing into GRASS.  I'm
not a heavy end-user, though.

Would it make sense to move this functionality to g.region to keep all
region related work in a single module?  A flag '-s' could be added in
order to set the region of a particular map (be it vector or raster).

I can see strong cases made for both modular and unified functionality.
