For what it's worth, I run a/b tests in my work where I consistently see large caching effects. For example, when we compare an experimental version of something to the currently deployed version it's critical that we cache-bust the control group. And changes that improve caching generally make things significantly better.
Caching effects are much smaller on Safari with its per-domain cache, but even there if something broke caching for us it would be a high priority to fix.

8mb JavaScript bundles to display their static homepage to a mobile browser that has maybe a couple hundred MB allocated to caching things
Thanks for that. It explains why even on very high-end new phones, switching between complicated web sites in different tabs causes a reload.
We're in an age where websites happily serve up 8mb JavaScript bundles to display their static homepage to a mobile browser that has maybe a couple hundred MB allocated to caching things. Sure, it may be there if you immediately load another page on that site (and the devs aren't using a bundler that serves a different 8mb next time).
But if they leave and come back, they'll get the same full download experience.
