Yes that is sensible. The question is whether we should enforce this

Maybe. I've actually been finding the magic selection confusing over the
last few days as I seem to get 'everything' even when I comment stuff out of
map lists. I haven't exactly got to the bottom of it so I haven't sent mail
about it (yet).
The problem with 'automagic' software is that it can be very hard
to work out what is going on when it is not doing what you want. Of course
my dataset with many caves and multiple maps is more complicated than most
so this probably isn't a problem (we should design to make the simple case
easy - the complicated case is going to be complicated whatever we do).
Let me do some more work on producing multiple maps from one dataset and
then we can discuss the whole issue some more. I expect there will be a
number of problems - like wanting to have labels and cross sections in
different places on different maps - I don';t think we have that option at
