Why are headers removed when the output is to a pipe or a file? This makes it really hard for me when I need to wrap the command with other tooling, or even just save the output. The output should not change based on where the output is going. If people want something w/o headers then let them ask for it via a flag.

Yes there's a --tty but I shouldn't have to do that to get the commands "normal" output to remain unchanged just because I'm sending it to a file.

this was done for easier grep-ability. grep-ing for things is a fairly common operation during regular dev workflow that would be hindered by having to add extra flags every time.

I get that, but then if people want the output that would normally be produced to be "more grep-able" then they should ask for it via a flag. By default "foo" and "foo > out" should produce the exact same output. IMO it's backwards to have to use a flag to ask for "untouched" output - which is what --tty is doing.
