Sorry but this sounds like they just didn't know how to write React and didn't take the time to learn it. You can write React and have 2 runtime dependencies in total - react and react-dom. Or you can go for preact and have exactly 1 runtime dependency - preact. Everything you need is there.
Time-to-interactive has never been a problem for me. My code-splitted bundles are so small they're pre-loaded quicker than the server-rendered HTML code. And builds? My apps - even big ones - build in single digit seconds (using swc or esbuild), and small ones like forms we're talking about in less than a second. The only thing that takes long time is TypeScript typechecking, I do that in a separate task in my CI while the build is long done and tests are in progress at the same time.
I'm not saying all this is super easy - obviously it's the product of using React literally since it's first public beta release. But it's also not impossible to do, and setting up a htmx and a server to run it on is IMHO similar complexity.
The biggest mistake people do - they use stuff like create-react-app with a bunch of absolutely unnecessary cruft. And then they follow some tutorials made by a dude who knows React for 2 months. Just read the React docs (except for the create-react-app part) and you're good to go.
BTW: jQuery is 85.1 kB minified and 29.7 kB gzipped. Preact (same API/dev experience as React, minimal performance impact) is 11.4 kB minified and 4.5 kB gzipped.
