Try publishing on https://repo.or.cz (or another old-style web interface), and just leave an email for contact.

You will hear only crickets.

Adding the slightest friction, and making potential drama 1:1 only, demotivates most people.

You might miss out on an occasional good feedback, though.

This is the way. You can also just decide to not accept contributions and feedback in general.

Further downside is that your project will have a harder time becoming popular, and being popular is secretly (or not so secretly) the motivation for many in open source.

Will be a lot more honest though.

I don't have my stuff on GitHub, but git push will send me email with a patch. I actually get real, useful patches out of it (more than before I had only email); not huge stuff, but scratching people's itches and bugs; stuff I can mostly just apply right away. I never get pure junk (e.g. the “I'm sure you want to switch to My Favorite Build System” patches, or AI slop). So somehow, for me, this is pretty much the perfect level of friction, it seems.
