No, they are is related.

My argue is: there is no generic rule which make Tuple!(X, Y) un-nested but
fun!A make nested. TemplateInstance::hasNestedArgs() works on the template
instance, so it cannot know the actual instantiated result is a type (from
Tuple!(X, Y)) or a function (from fun!A). It's time paradox.

To implement your argument, we need much special code to support the case.
It increases the compiler complexity for the much less benefit.
