when i first heard "hey you should use git switch" it was like, two years ago. and i was like "sorry i don't use newfangled commands until they make it into the distro package" and that's when i learn switch landed in august 2019. oops, lol
one personality defect of mine is that i don't think checkout is "five commands in one" or whatever, it's just one command. just horribly brain broken in the same way git was
