These days, batching DOM updates doesn't give you as big of a win as it did in the past (browser tech has improved, browser engines do more batching under the covers, etc). Also web components tend to use more modern layers of the web stack (style isolation, shadow DOM, etc) - which allow the browser to perform more optimizations, as well. I think we'll find that they become more performant over time. Also consider that some "native" html components are effectively implemented the same way as web components these days. Often you'll find that React/etc are perf hits (vs finely tuned components) because their declarative nature tends to lead to unnecessary work …which is totally fine 99% of the time, because the productivity win from that is HUGE.
