Transpilation and bloat are orthogonal. Javascript being bloated or not is also a relative: consider Python, which is much slower than js, and much more memory hungry.

To further argue your original point: chrome & electron are the only reason desktop is still around, both Microsoft and Apple tried their very hardest to build a walled garden of GUI frameworks, rejecting the very idea of compatibility, good design, and ease of use, until they were surpassed by the web, and particularly Google, showing that delivering functioning applications to a computer does not require gigantic widget libraries, outdated looks or complicated downloads & install processes, but is in fact nothing more than a bit of standardization and a couple MBs of text.

All this electron & web hate is so incredibly misplaced I don't even know where to begin. Have you tried making a cross platform mac/win native app? I have, its like being catapulted into the stone age, but you're asked to build a skyscraper.
