I think using the first param would be better, yes
(in the general case, you can have
```cpp
template <typename>
void f(auto);
```
so to establish if there are abbreviated parameters, you need to look at the
first one,
(and getTemplateLoc is always valid)
but in the
```cpp
void f(auto)
```
case, there are only abbreviated parameters, and you can point to the first one
(and getTemplateLoc is never valid).
Does that make sense?
