In no way was what I wrote intended as a personal attack. If this is how
it came across, I sincerely apologize.

Up to now you are the only one who has raised this issue as a problem.
Maybe this is because you are the only one conscious of it and many people
are actually misusing gis.m thinking that they get a precision which they
are actually not getting. Maybe it is because those who need such level of
precision have the habit of going through g.region. Or maybe it is because
those who need it are working on the command line and so don't use gis.m.
I don't know the reasons...

So, the first question to be asked is: does everyone agree that this is a
bug ? If yes, then I agree completely that this needs to be fixed. But as
always developer time is limited...and there are other bugs in GRASS which
those who have the skills find more important.

The current situation definitely is not easy as we are in a transition
phase between gui's with a very important step being gis.m, but at the
same time this is already poised to be replaced. This makes the issue more
difficult, as Michael has to deal with three different GUIs at the same
time, and it is not always clear which of these should be the priority.

I am willing to help you try to identify whether there are possible
solutions to the issue in gis.m, but definitely not before next week and
as Markus wants to release 6.2 tomorrow, I am afraid it will have to wait
for a bug fix release.
