Not only in theory, I actually use it all the time :-). And you can
achieve the same by setting all the areas outside your target area to
NULL. I like how the combination of the two gives you a fine control
over how you want to sample an area. You can even do the same with the
cover layer. Although to be honest, I don't really see the added value
of having this option to define a cover layer, but that is another point.
By the way, it seems the issue of under-sampling was solved too? At
least, in the limited trials I did, when generating random points I am
actually getting the requested number of sample points, which I didn't
previously! Super!!
Cheers,
Paulo

Thanks pointing it out. I have actually used the script some time ago. I
think I found that it becomes a bit slow when working with large number of
points, but I am going to try in grass 7, see if it is any faster due to
faster vector handling.
In theory, r.random should work for irregular areas if you set a MASK.
