It would be nice to be able to set a region to a specific vector feature.
For example, if I have a vector map of states boundaries, and I want to do
computation on a specific state, I have to first extract the state I want,
then set the region. When working in a loop, it is a burden.

The same option has been added to r.mask (See #1838).

Comment (by sbl):

You can do that already (though in two steps) using first v.db.select -r.
See:
https://grass.osgeo.org/grass72/manuals/v.db.select.html

Check example for:
"Print region extent of selected vector features"
