Can be "made with JS" doesn't mean that by chance it would be in any bit better than long proved and still used solution - not a one of many crippled, always changing, excluding imitations of it - for example like that one: https://news.ycombinator.com/item?id=45183624 (no caching, not instant, transparent or othogonal etc.).
With XSLT removed, Chrome can not claim to be a standard internet browser neither.
There is nothing wrong with XSLT - it's just Google not wanting to fix few bugs since decades - but others have to follow, nothing changes.
Actually.. I can't care less about Chrome - if others will not follow neither allow Google to reach such position claiming to be able to dastandardize working and used solutions.
