Why not set Emacs development workflow based on the popular git forges (GitHub, Bitbucket, Gitlab, ect)?

[Hongyi Zhao]

Nowadays, the large software projects often conduct the development on
the workflow supplied by git  forges (GitHub, Bitbucket, GitLab,
etc.). But it seems that Emacs is still developed directly on git, as
described here [1], which makes maintaining GNU Emacs development a
lot of extra work.

So, why not set Emacs development workflow based on the popular git forges?
