Model is a great way to "model" all new databases. Unfortunately there are two limitations that I encounter often enough that I thought I would file an enhancement request:

(1) you can't turn off this inheritance; in order to create a non-model-based database, you must create the database, allow it to inherit everything from model, then create a script that drops all of the user-defined objects.

(2) you can't set up inheritance for database settings such as ALLOW_SNAPSHOT_ISOLATION. Several times now I have forgotten to turn this on and while it's easy to correct it would be great for this type of property to be editable on model.

I went over some similar ideas in Connect #415343, but those revolved more closely around tempdb (which automatically gets re-created from model when the service restarts - here I am talking about creating databases manually).
