For me it is a serious nag. And I come from Ruby, where, with Rails, startup time is abysmal. So I am used to something.
Don't people use the watch options so they don't need to interact with the app to have it rerun things? I don't think speeding up how long scripts take to start will change that.
Same for (re-)starting webservices and such. And when not available or applicable in my editor, GNUtools, bash and unix offer plenty of tools to easily do this for me. E.g. https://linux.die.net/man/1/inotifywait to fire a command (e.g. restart a service) on changing files.
I presumed these `--watch` where there to solve the slow-booting issues only (like in Rails) but maybe they are there because someone didn't know their OS and DE could do it for them already and decided to build it into the suite or tool instead of using existing tooling?

You should look up what "git" means in English :)
