There's lots of prior art, such as https://wheelmap.org/ -- so I imagine OSM is somewhat open to this sort of thing. Might be worth looking at how Wheelmap edits OSM. I believe it's from a generic account and edits are tagged such to make it clear it's from a member of the public.

You could also implement OAuth (sign-in with OSM) to do edits, similar to how some tools like https://maproulette.org/ work, though you'll get less contributions if you don't have an option for anonymous public edits.
