I recently replied to SO question with a "New feature have been added that supports your use case: link" that was genuinely solving a problem.

Reply got removed by a moderator saying that I need to describe solution and can't just provide the link. I didn't bother. Currently the only answer suggests sub-optimal solutions and I am not replying to SO questions again.

It felt like a land grab - it wouldn't help the questioner, but it would help SO, by bringing more data to their platform.
