If I have to choose between no PR and a "drive-by PR" where the author doesn't understand the changes to have a discussion, or isn't available to do changes and expects me to "take it from there", then I'd much rather go with "no PR" for the sake of everyone.

On the third hand, pestering and shaming open-source maintainers because they don't accept your PR is how you get the XZ backdoor situation.

There is a different dynamic between this and that.
