is there a reason why Magento shouldn't support uninstall/downgrade for modules

Question

Automated instant rollback is an important feature of enterprise-grade deployment mechanisms. Currently, it\'s not possible to achieve this using Magento\'s built-in instal

Answer 1

Note: Perhaps this is not applicable to Magento.

I usually view database application upgrades covering two main areas: 1. code 2. database.

Code updates are easy to roll back. I usually manage this separately of the applications upgrade/management code. I usually use a the OS's file system to provide me with "instant rollback" functionality. Where database roll-backs are concerned, things get more complicated. One could take a similar approach with the database as well. However, it would only be realistic on a test system.

If it's only code rollback that you are concerned with, I'd use something external of the application itself to manage this. It can be thought of as a snapshot I suppose.

If Magento doesn't support this out of the box, I don't think it would be wise to tack it on. It seems like quite a core requirement that if not planned and coded for from the start, will be rather tricky to implement.
