It's reasonable not to take action based on the feedback from a developer who sells an app-level firewall - it's neither a broad nor disinterested constituency. Big Sur's been out for less than two months - for a bigass company, it's decent turnaround.
Who else would Apple take feedback from during the betas? Who else would even notice that there was a hole in the firewalls except the firewall developers?
The gigantic majority of users who are not firewall developers as well as the gigantic majority who never touches the betas both seem like sensible and important sources of feedback.

I was replying to a comment that literally said, "That's why Apple has the Developer and Public Beta releases for iOS/OSX", so maybe you should argue with that comment instead of with me.
