I agree with everything except

> this will create pressure on developers to memory-optimize their software

Ideally, yes, realistically, no. It is rare that I hear FE devs considering how much memory their apps are using. I really wish RAM use would be a much greater concern, but when I look at programs I normally run, I can tell RAM is not a concern (imagine me giving a dramatic accusing look at Docker Desktop, next-server, ...). RAM use for web pages is often not given much consideration either.
