Why is "guessed "dir" filetype based on contents" a warning?

I'm moving the discussion from #2065 to here.

Is the "guessed "dir" filetype based on contents" message really helpful? Starting vd on a folder is the 99% use case for me. I don't need VisiData telling me that it was just scratching its head every time I open it.

There is a git filetype, which is why that guessing information is there. It's to let people know if it was opened as a git repo or dir repo. That has bitten me once before.

Okay, but why is it a warning though? My general understanding of warnings, not specifically with VisiData, is that they mean "you did something slightly wrong" (relevant standup bit.) When a warning becomes part of everyday usage people just become numb to warnings and ignore them, which is more dangerous.

Interestingly, the warning doesn't show up when you run vd but only when you run vd some_folder, even though the former opens a folder as well.

This is because, in the former case, we know we're opening a folder, so we specify the filetype explicitly. You can get the same effect by using vd -f dir some_folder.
