I would. I already use FF mainly under a locked-down profile for mere reading. (I use another profile for madatory interactive sites like banking and stuff).

Others like me would. And resource-constrained devices. An eco-system of low-tech sites could emerge with a label signaling them as simple and virtuous.

So you basically want gemini? https://en.m.wikipedia.org/wiki/Gemini_(protocol)

Interesting. But I meant only using a subset of current web stack, and insist on low resource.

The issue I have with Gemini is that it discards 25+ years of established domain knowledge and existing software for something which does not provide any additional functionality over what today's software already offers.
