Worth a shot! The first few days are by far the worst while all of the existing connections are accounted for, but things calm down quickly.
One thing I wished I knew sooner was that the square [+] button on the rule dialog opens more fields on the form for editing.
This makes it super easy to create a single wildcard rule e.g. when timesyncd tries to hit an ntp server for the first time, I expand the autogenerated rule that pops up to include all subdomains like *.ntp.domain.tld so I don’t have to keep creating rules for the other ntp servers. I’ve gotten more efficient over time this way.
The experience is much closer to the other common permission prompts I mentioned which is why I asked how you feel about them.
As a fellow multi-decade dotfile tweaker, that experience isn’t comparable and is not a good model for judging this tool.
