I think that I implemented it to support myself in downloading satellite
data from the NASA data repository. They always want LatLong for project
areas. So I added -l, and g.region tells me immediately the current
coordinates in LatLong. Copy-paste and I'm done.

So that's a vote to change g.region. I tend to agree, because a
reliable WGS84 output is better than a sort of undefined LatLong
output with current datum/ellipsoid.
