That's condescending. There is, obviously, a use case for in-core text search. E.g., mine is that it's better to waste a few CPU cycles in the browser than on the server. And Javascript runs pretty fast, and has been doing so for years now. And while a Javascript implementation won't beat a well-programmed C/Rust/Go version, the fact that it's in core helps it speed undoubtedly. So, if you ever need a web user to search some moderately sized set of texts, this might be really helpful.
As a matter of fact, I have a similar module in my applications, e.g. for typo resistant searching through help docs and hierarchical menus.
