that's why it needs an overhaul :-) Go to, for example,
examples/bing.html and in console type 'map.projection' and
'map.getProjection()' - confusing, or what?

Bart, AFAIA map.projection is only used if projection is not set on
the layers, so it's a convenience to enable you to set projection once
for all layers instead of having to define it on all layers. If that's
correct, perhaps it would be better to make map.projection not api,
and have it documented as a constructor option instead.
