Regex Engine Internals as a Library
https://www.cs.princeton.edu/courses/archive/fall19/cos226/l... and https://kean.blog/post/lets-build-regex are excellent introductions to implementing a (very) simplified regex engine: construct a nondetermistic finite state automaton for the regex, then perform a graph search on the resulting digraph; if the vertex corresponding to your end state is reachable, you have a match.
I think this exercise is valuable for anyone writing regexes to not only understand that there's less magic than one might think, but also to visualize a bunch of balls bouncing along an NFA - that bug you inevitably hit in production due to catastrophic backtracking now takes on a physical meaning!
Separately re: the OP, https://github.com/rust-lang/regex/issues/822 (and specifically BurntSushi's comment at the very end of the issue) adds really useful context to the paragraph in the OP about niche APIs: https://blog.burntsushi.net/regex-internals/#problem-request... - searching with multiple regexes simultaneously against a text is both incredibly complex and incredibly useful, and I can't wait to see what the community comes up with for this pattern!

I was wrong about rust
Tangential FYI: I'll be releasing a regex-lite crate soon, which should help binary size and compilation time for cases where you don't care too much about regex performance or Unicode support.

regex 1.8.0 released (no-op escapes allowed, (?<name>re) syntax added)
The rewrite is done. It's in this PR: https://github.com/rust-lang/regex/pull/978
This is a big release, but will be "soon" followed by an even bigger release that rewrites the entire regex crate. The regex crate will be turned into a thin wrapper around regex-automata APIs: https://github.com/rust-lang/regex/pull/978

Introducing Hitori – generic compile-time regular expressions library
I'm sorry but that's complete nonsense? The regex crate doesn't backtrack either, by design. And not backtracking is a very desirable property from a security & consistency perspective.
While regex has a backtracking engine, it's bounded and only there as an optimisation, and advanced uses via regex-automata should eventually allow disabling it without changing any of the engine's features.
