Rule 2b is very difficult to check because it requires to keep an history of the p2 repository over time. Also, rule 2a makes the files more explicit, easier to humanly guess what is going to get into SimRel (but that's more a comfort thing)

>> How would fully-qualified versions be a way to continuous release?
>> ========================================
>> In order to get continuous release, it is necessary to have reproducible and traceable builds. Indeed, let's imagine a project contribution is "flexible", it means that we do not know how much the current build output would differ from the previous one (it's issue 1). Continuous release requires that we always know what changes, to make sure that the change is acceptable for being released. So we need to know what changes, always, and to check it.
>> Checking automatically that projects conform to rule 2 can only be done in the case of rule 2a. So we need 2a to automatically get 2 to automatically be able to trust contributions and allow             continuous releases.
>> Another important step for continuous releases is the enforcement of Gerrit and code-review before the merge. If all contributions go through Gerrit, we can add some automated tests on Gerrit to guarantee that the contribution is valid from SimRel POV (that can be license check, or even an install test, and even manual tests for some contributions that are known to be fragile...).

>> If we get:

That might be an interesting topic for a panel on Thursday (discussing the fall-out of that keynote), but that highly depends on the content of the keynote and what the architecture council have to say about that. But maybe that is a different panel discussion then, not the meet-the-architecture-council thing, but more something like “what do you think about the future of IDEs”, probably with a different set of panelists than purely the AC.
