Some gpus need SIP on off because the drivers won't run else. I generally also have to disable it because I run some apps and modify some underlying behaviours in macOS that I find undesirable. I don't think it should be any worse than running stuff as sudo on Unix, where you can easily break the whole OS if you, as the user, don't know what you're doing.
Chrome had a bug and even if it wouldn't have broken the system had SIP been enabled, it's still a serious bug on chrome's side.
