There's no point announcing things are now "legacy". Legacy is what Microsoft invented to call products they just made a competitor for, and the psychology seems the same. If it doesn't fit your needs, great. But React is useful for lots of needs.
I didn't mean React is legacy. You can't replace a React app with HTMX in general. I just meant within my project. Those parts are now unmaintained and will be replaced when they break or if we need to change them.
