24235	Deprecate is_usable attribute on template loaders?	Preston Timmons	nobody	"Each Django loaders has a boolean attribute of ""is_usable"". It seems the only use for this comes from the egg loader when setuptools isn't installed. If ""is_usable"" is false, a warning is raised in engine.find_template_loader, but otherwise the loader is silently ignored for template loading.

It seems like that is the wrong behavior. I think the loaders should fail loudly if they're missing configuration. Otherwise, it's unclear why they're not used to find templates. I ran into this when writing a sample loader and forgetting to specify ""is_usable"" as True on it.

Unless there's a use case for silently ignoring template loaders, I think we should deprecate this behavior."	Cleanup/optimization	closed	Template system	dev	Normal	fixed			Accepted	1	0	0	0	0	0
