This evangelism around HTMX is bit misplaced.

First - simple use cases sure great. But imagine you have to update some element out of the from tree. Now you need to have OOB swaps and your HTML must contain that fragment.

Not just that your server template code now has to determine if it is HTMX request and only render OOB fragments if so.

Even at decent size app, soon it turns super brittle.

Yet to talk about complicated interfaces. Let's not go complicated just think of variants in an E-commerce admin panel.

3 variants with 5 values each these are 125 SKU rows that must be collapsed group wise.

htmx can do it but it's going to be very very difficult and brittle.

So it is surely very useful but it is NOT the only tool for all use cases.
