This is not affected.

You get wrong outputs. I forgot about this possibility.

Not clear to me when did you get this.

What about official
g.mapset/g.chmapset/g.set/g.reset/? gisdbase= location= mapset=
which would check if the mapset is in use, reset variables and run d.erase?
This should be in 5.7.0, I think. Otherwise it is too dangerous.
