Chrome is basically reinventing each OS API and libraries. One day they’ll have their own tcp stack and packet filter.
It kinda makes sense given that one of their major products is a computer that runs an operating system literally called ChromeOS.
Chrome still has a way to go until Zawinski's Law is satisfied natively.
Arguably with QUIC it already does.
