Sort of. I suspect an under-appreciated part of the modern Web performing so poorly is how casually we throw in vector graphics (SVG, mostly) and draw/transform shit with CSS, these days. Those
used to be things one simply did not do without an excellent reason, because they're computationally costly for the client. In maybe a couple years' span they went from "wait, don't do that, it's bad for your user" to "LOL SVG icons are so convenient, let's use them everywhere, and then maybe skew and manipulate them with CSS at runtime because why not".
[EDIT] To clarify, this is relevant to cutting bytes because encoding graphics with SVG or drawing them with CSS can mean shipping fewer bytes than JPGs or whatever.
