I don't think they should be standard at all. I am familiar with all of them pretty much since the moment they are born (which is not that long, TBH) and the only one I actually use is tree. Which is also quite a judgement call, since it can be replaced by exa, which is more powerful (I'm considering it; I'm pretty sure that you will like it, BTW, so take a look). bat is useless, since there is vim/view. rg is actually good, but cannot be used as a drop-in replacement for ag (I don't remember what the problem is exactly, but I tried several times and burntsushi even gave me some advice on that, and I still use ag, which is slower, so I assume there actually was some serious reason). And, by the way, no, neither of them is actually a replacement of grep. (Also, yeah, let's ignore that Rust in the standard libraries is still a problem.)
