I'm thinking of launching a new app where a single click share would be a feature worth implementing, but definitely not part of the core functionality. I'm trying to figure out if this feature is worth implementing at all, or it's just asking for trouble.

I always appreciate shareable permalinks (if that's what you mean), but I think that's a different question than SEO.

Personally I would expect share links to be unlisted (not indexed by search engines, not publicly discoverable, with a long enough uuid to be effectively unguessable). "Publish publicly" could be a separate function you add later, with moderation?
