Speeding up the build could be done in other ways, were they using esbuild or something fast previously? Probably not.
The memory usage saving is really not a big deal, load up your favourite news web page and look at the memory it chews up in comparison.
As for the preference implied for python over js, that's fine, but the choice is not binary, typescript is my preference for a React project, for example.
Reduction in LOC is slightly misleading, JSX creates a lot of lines.
It would be interesting to see a proper write up on the data React couldn't handle.
Agreed. More details are necessary to understand the potential benefit of such rewrites.
And to be honest 21K LOC is not a big project. I can imagine that as project grows even larger, there will be problems that htmx cannot or is difficult to handle, and I'll be curious about how that would work out.
