> They're not exactly as supported, because they're not on by default

I really don't get this. In almost any software there are features that are not 'on by default', but it's still implemented and supported (except explicitly stated otherwise). How can this be a reason to not use the functionality when you need it?

It's like using Outlook to respond to mail on a mailing list. Sure, it's theoretically possible to use some combination of manual configuration and extra work to construct a post that won't violate social norms, but the tool doesn't encourage it, so mailing lists with a significant number of Outlook users on them tend to fail to follow the standard mailing list conventions of other lists, and develop their own conventions.

The same holds for any tool used in a workflow that involves anyone other than yourself: any tool with a default workflow tends to encourage people to follow that default workflow.
