I am thinking of situations where there is a natural atlas, but where the elements of this atlas are not naturally parameterized by points in the manifold. Then having only the
chart_at as members of the atlas would be very artificial.

What about using default/auto arguments?
Sebastien Gouezel (Mar 07 2021 at 08:44):
If you encounter situations where they would be useful, yes, sure. But I feel in most situations there will be a nicer description than indexing by the points in the manifold, so I don't envision the default argument being used often. Are you thinking of a particular example?
