Why would I write my own JS when "hx-get" does the job? Writing your own JS makes sense in some cases, but using HTML partials is also useful in many cases where you need to talk to the server anyways (since they e.g. prevent logic duplication). HTMX just makes it easy to work with them, as they're a single attribute away, rather than doing the request and insertion by hand.
Native clients are deliberately out of scope, but scraping HTML isn't the suggested solution. Rather, it is having a JSON API next to the hypermedia API: https://htmx.org/essays/splitting-your-apis/. This does have the downside of duplicate work, but does bring stability to the API without introducing something like GraphQL.
And yes, you will need to learn HTMX to use HTMX. But the surface of HTMX is generally quite small, and composes well with knowledge about HTML/CSS.
