I mean, there's room for both things. It would be bad if nobody at all was willing to fawn over a new project and call it exciting instead of shooting it down. (After all, it might be my project ...)
Shouldn't be sensitive about people asking "why didn't you do this?" though, or "that reminds me of my own thing that I made back in the stone age". Those are useful and reasonable points, if not made unkindly. Reality is unkind.
