Doing a diagnostic would mean finding all the places where we form a `TemplateParmPosition` and ensure we have enough source location information to issue the diagnostic. Given that we don't expect users to ever hit it, having the assertion gives a wee bit of coverage (godbolt exposes an assertions build, for example) but without as much implementation burden. That said, if it's easy enough to give diagnostics, that's a more user-friendly approach if we think anyone would hit that limit. (I suspect template instantiation depth would be hit before bumping up against these limits, though.) > I can't imagine a scenario in which someone would hit these limits and have > assertions enabled.

I think people instantiate to deeper template depths than they typically have for template parameters, so having a deeper depth made sense to me.
