Hope so :-)

Sorry, I'm not saying that we need to have the ability to set the last
stop to _any_ value but just to select 3m or 6m as this is widely
discussed issue at technical divers and common in "competing" dive
planning software.

Otherwise I'm with you Linus saying, there is no really sense in 1m
stops but one should use the smooth mode instead. Maybe it would be nice
to be able to limit the smooth calculation to a last stop as well, lets
say at 2m!? But this is just a minor issue and would just be for
theoretical discussions. I'm wondering how we could something like a
runtable for smooth mode generated profiles anyway...
