Yes! (With caveats.)
If you take a look at the support tables on @caniuse, native support is pretty uneven across the browserscape: https://caniuse.com/#search=components …
That said, there are polyfills that make web components cross-platform.
A lot of it comes down to how much JavaScript code you want to ship and whether the trade-off of code to end user benefit is worth it.
For a fantastic discussion of these tradeoffs, JavaScript, developer convenience, and user experience, I highly recommend this piece from @slightlylate: https://infrequently.org/2018/09/the-developer-experience-bait-and-switch/ …
Or there’s this piece I wrote along similar lines:https://www.aaron-gustafson.com/notebook/who-should-pay/ …
Apologies for missing your piece. On the Variables (etc.) thing, there's a question of evidence. E.g., while new features add some cost to style recalc and layout, those phases aren't what's slowing down the traces i see. JS, however...
Also, on the Web Components front, IE/Edge are scheduled to be the only browsers without them by EOY. As those are mostly desktop-oriented, you can more easily afford some small polyfill overhead there. Mobile browsers nearly all support WC.
Of course there is that pesky JS dependency…
