Hah. I hadn't realized I was taking that for granted (over multiple houses myself), and just figured they were required by code (even though it makes the chrome sink shutoffs kind of redundant). Score 1 for DIYers doing more maintainable work than professionals. FWIW a SharkBite valve or NPT adapter into a valve would seem to be a handier thing to have around than a pure cap. For example, you can attach a valve without shutting the water off.
