maybe its the fact that its really easy adding something like this, and this (I think) or something which basically acomplishes the same thing (but in a better way?) are used by some major meta frameworks like nextJS etc.

I guess it has limited applicability but maybe its the small little gains that add victories. I really may be going on in a tangent but I always used to think that hardware is boring / there aren't too many optimizations its all transistors with and,or,not but then.. I read about all the crazy stuff like L1 cache and the marvel machinery that is known as computers. It blew my mind into shredders. Compilers are some madman's work too, the amount of optimization is just bonkers just for tiny performances but those tiny performance boosts in the whole stack makes everything run so fast. Its so cool.
