We're talking about a template function whose body is visible to the compiler.
The chance that such a function would be inlined is greater than 90%.

So what problem are we really solving if the function did get inlined?

I don't think there is a problem that needs solving in the first place. Please
provide a concrete case (or preferably three) where you've found that not only
the compiler made a bad decision, it had no sufficient information to make a
good decision in the first place.
