I have one and it’s very nice.

That’s why I included Perl, it is always there. Just don’t code as if you were in the nineties and Perl is a perfectly legitimate language, even more so for shell tasks. Bad and good doesn’t depend so much on the language but the coder.

Why not use Perl or python for scripting tasks? Bash script is terrible imo.

Fzf doesn’t need fish, though. I use it with bash.

And language tool is a great option! I use it for many different languages and support for it can be found in many places. Even Thunderbird has first class support for it, these days!

Stable, in this context, only means, that there are no major version jumps. So, you won’t update from, say, version 3.4.9 to 4.0 if that comes out, but instead to 3.4.10, which provides stability, but no new features. It depends a lot on your usage profile, if this is important to you. In that sense, the AUR usually isn’t very stable – but that can be seen as a good thing. If it is significant, typically, you can find pinned versions, too, just as you are still able to download python 2 (not supported for years, but it’s there, stable).
