"*WANT* to close or *WANT* to merge". Not WILL close or WILL merge.

You look at the PR and you know just by looking at it for a few seconds if it looks off or not.

Looks off -> "Want to close"

Write a polite response and close the issue.

Doesn't look off -> "Want to merge"

If we want to merge it, then of course you look at it more closely. Or label it and move on with the triage.
