Using Heroku as the primary Git Repo

Are there are any drawbacks of using Heroku as the primary Git repo - as a rep开发者_StackOverflow中文版lacement for Github ?

Heroku isn't a replacement for GitHub (and certainly don't have all the social feature, pull request, fork queues, reviews and comments on commits...).
Plus I don't think it supports smart http (which is important when you are pushing behind an enterprise firewall).
And it doesn't support submodules (GitHub does)

But it is adapted for managing and deploying web application, and has advanced monitoring feature. If it is your case, then Heroku is the right choice.
