First of all: I agree that this is bad and that these developers should choose portable tech when building these sites.

But as of now, Chrome is and has for a long time been the only browser to support:

Shadow DOM: https://caniuse.com/#feat=shadowdomv1

Custom elements: https://caniuse.com/#feat=custom-elementsv1

CSS Paint API: https://caniuse.com/#feat=css-paint-api

That's been in Chrome for, like, less than a year - hardly a "long time". And the implementation leaked history spectacularly [0]. Rushing features out the door isn't necessarily something to be proud of.
