Totally agree, but as long as we do not have this I'd just like to be
able to use it the way it is.

Hm, I'm just saying that there are people how do not 3m but 6m stops as
the last stop. Personally I do 3m and would like to be able to do 2m or
even 1m if my dive computer or dive planning software would allow this.
Mind the pressure difference when surfacing from 6m (1,6bar to 1bar -
60%!) or 3m (still 30%) and compare this to a ascend from 90m to 80m
Anyway, defining a last stop should be included in subsurface at the end
of the day.
