This is exactly it. Regex is super simple. The difficulty is maintaining a mental mapping between language/util <-> regex engine <-> engine syntax & character class names. It gets worse when utils also conditionally enable extended syntaxes with flags or options.
The hardest part is remembering whether you need to use \w or [:alnum:].
Way too few utils actually mention which syntax they use too. Most just say something accepts a "regular expression", which is totally ambiguous.

Depends on what you're doing in your config and what you're changing. My configs are huge and complex because I was a moron when I first started out. Adding packages to your nixosConfigurations is a smell IMO. Most of the time, it would be preferable to add them to a devshell instead.
25 seconds sounds pretty close to my experience, but my machine is beefy and my configs have a lot of bad patterns for eval time.
