What is considered vibe coded and slop?

Where is the line?

Drew draws the line of any introduction of AI in any OSS project. (1.) (2.)

Vim, Linux, OpenBSD have AI in them now, even a small tinge of it, so that would be considered slop.

Is it now with some effort with AI assistance that is acceptable or unacceptable or is it still slop?

Or is it more extreme that an OSS project should absolutely not have ANY AI at all to comply with not being slop?
