Fedora and fallback DNS servers

Here we are talking about a situation that happens if your DHCP server has a certain specific broken configuration.

All other broken DHCP configurations will still make you unable to connect to anything, the default DNS only prevents one of thousands of ways to break it.

At this point. Is it worth the privacy implications when it's a thing that already normally never happens and if it happens it breaks networking on every OS?

Don't get sidetracked about technical vs non technical.
