I've just discovered this very old and powerful utility, seemingly a drop-in replacement for standard grep with a lot more power:

https://ugrep.com/

Normally I would expect something like this to definitely be in the main portage tree. Any idea why it's not?
Is there some reason why this has been explicitly rejected for inclusion in Gentoo? Or is it just an accident
or coincidence that no one has stepped up to put it in and maintain it?

Looks like an older version is in guru:

I can't tell from a quick-ish look if it's the same thing, but there was a bug offering it to be included, but it seems to have somewhat disappeared back when:

Depending on the advantages you are after, there's also ripgrep and ripgrep-all packages in Gentoo.

Thanks all... after posting this I discovered ripgrep(-all), and I think that's a better choice for my needs :D

Out of curiosity, how is it better than plain old grep, or what is it better for?

I think it's faster, but the main advantage for me is replacement strings and references therein:
Code:
rg 'foo(pattern)bah' -r 'bah-$1-foo' wherever

if I got that right, will output "bah-pattern-foo' for every occurrence of 'foopatternbah' in files below wherever.

I see. Well, I've just been using sed for this kind of more complex operations. Doesn't look much different: sed -n 's/foo\(pattern\)bah/bah-\1-foo/gp'
The whole appeal of grep is that it's a simple shortcut to a very frequently used command... Like: [G]lobally / [R]egular [E]xpression / [P]rint

Ah, but ripgrep does all that grep does, and saves two characters typing, as the command is rg instead of grep.

One difference between rg and grep - rg always searches a directory, so it's the same as "grep -r"
