I fear we're regressing.

There is a concept in browser UX design called the "line of death"[1] - the delineation between trusted browser UX and untrusted website UX. Unfortunately, because it looks ugly, every new year of visual designers further weaken its guarantees.

Here's an interesting anecdote from an earlier time. In the 2000s, back when the internet was a lot newer, and UX best practices were much less well understood, and internet users were starting to see the first big wave of "evil" websites, many of us independently discovered a surprisingly simple and surprisingly effective mitigation. If you choose a custom browser theme, preferably with bright colors, websites can't fake browser UX elements. The default theme will clearly mismatch, and websites can't guess what theme you did pick.
