I was under the impression that that happened already for both
scenarios.

I'm pretty sure that's not needed, both from memory and from
a quick grep of the code:
grass65/raster/r.proj$ grep color *
main.c: orows, ocols, have_colors, /* Input map has a colour table */
main.c:have_colors = G_read_colors(inmap->answer, setname, &colr);
main.c:if (have_colors > 0) {
main.c: G_write_colors(mapname, G_mapset(), &colr);
main.c: G_free_colors(&colr);
grass65/imagery/i.rectify$ grep color *
exec.c: colr_ok = G_read_colors(name, mapset, &colr) > 0;
exec.c: G_write_colors(result, G_mapset(), &colr);
exec.c: G_free_colors(&colr);

if you like, Glynn's new r.colors.out + 'r.colors rules=' will
do that outside of the automation.
