In my setup those keys only apply at BOL in a heading line.  I never
type anything there.

TAB for reindenting might be a bit trickier.  Apparently I never try to
reindent a heading line when point is at BOL, because I never thought
about a possible conflict, but I guess I would type SPC TAB in that
case.

I can't find this block in outline.el, is this a suggestion for a
possible default?

Okay, those keymaps are active in the entire heading line, right?

I would prefer to only have a special behavior at the first character of
a heading line, in exchange of allowing _any_ shortcut key with minimal
interference.  Org mode already does that with a simple customization,
(setq org-use-speed-commands t), so I don't think it would be too
surprising for most users.
