It isn't a catastrophe, but there are some negative effects.  For
example, it puts the Outline menu on the menu bar, but most of the
items there will either do nothing or signal an error.

It is also confusing to see "Outl" on the mode line of the Help
buffers, but only in some cases and not in others.  It means whatever
features that could be useful to Help are only sometimes available.

If some Help feature can benefit from outline-minor-mode, it should
turn that mode on by itself, not rely on that being set already by
some other code.

Thanks, I think this should be installed on master (assuming that it
solves the problem; I didn't have time to try it).
