I would like to invite you to add your concepts to GitAlias. I'm the maintainer and I see much value in microservices.
However, something i see that can be done with the current script is to automate the process of opening a PR that cross multiple repos. A command that similar to `git flow` will flip various branches in various repos that match maybe a certain regex .. and then allow user to input the PR details (maybe based on a PR template as well) and then submit those to Github. On success, it will again add comment on each PR with a link to the other issues so that you have the Github issue reference link in there.
I am not yet sure if that is feasible but it seems an interesting thing to do and worth looking at
> We currently have a good 50+ git repository. Developing features affect very often more than one of these repos.
