Naah I think it’s super useful to know a bit about all popular distros. This makes you able to actually take part in conversations about what distro to pick for example.
I’ve ran them all at some point in my life, which makes me able to understand that it’s not just “different package manager” as some people say.
I mean, people say that, but for me it wasn’t a problem, I just picked one when I got started. Didn’t feel like a major decision since you can just switch again if you are unhappy.
