I'm not "fine" with it, but when there are trade-offs to be made, I'm definitely going to weigh that side less. Some people browse the web with javascript disabled. It's already a huge pain to browse the web with javascript disabled. With those two factors in mind, if I'm deciding whether to add javascript fallbacks (eg. SSR) on for my next project, I'm going to weigh the interests of the "javascript disabled" people very low. I don't have any animus against them, but at the same time I'm not going out of my way to cater to them either.
