depends what you want to do with the map. When focusing on routing outside
the mall: yes, when interested in routing for far distances: doesn't matter,
when interested in routing inside the mall you'll prefer to have details and
won't care whether it's connected to the outside...

yep, that's a small problem

IMHO the better the outline is matching reality the better you will
recognise the building (but we could have several outlines for different
heights, I agree, e.g. a tower-building/skyscraper often has a bigger base
and gets taller due to zoning-laws)

I do generally both.

everyone is free to map whatever he/she likes. As long as you don't delete
footpaths mapped by other people because you don't consider them relevant,
that's not a problem.
