Why can't a null-reference exception name the object that has a null reference?

Question

It seems to me that a lot of my debugging time is spent chasing down null-reference exceptions in complex statements. For instance:

In release builds, the variable names are stripped out from the symbols and the code might even be optimized to not have a specific memory location for a variable, but just keep the reference in one of the registers (depending on the scope of the variable usage). Thus, it might not be possible to deduct the name of the variable from the reference location.

In debug build, there's more information available about the variables. However, the exception object needs to work the same way irregardless of the build flavor. Hence, it acts upon the minimum information it can access in any flavor.
