Our application has many interdependent modules and we have to publish all of them to enable debugging in our personal area. This is a time consuming process that, to fix a bug that we expect to take 5 minutes, the overhead of an hour to get our Personal Area set up is too expensive.
Instead, we spend 15 minutes in our DEV environment to fix it due to conflicts with testing from other developers and qa who hit our breakpoints there.
If we could have our environments updated from an API call, then we can issue the request to update the personal area with all the modules in the application and then when it is ready we can start debugging the issue there in isolation.
