 Maybe it should do that when --debug is used?

 Why it should bloat out the output? It happens only when an exception
 is thrown and it is very useful detail. I think MS introduced this in
 .NET 2.0 too.

+It bloats the JIT output. For each cast failure condition we'd need to
+save the target type and the source type (specially the latter may be
+costly wrt register allocation and code quality). This will also
+require additional arch-specific trampolines. We're likely talking
+about 10-30 additional bytes of generated code per cast, depending on
+the architecture. Of the additional info it provides, the target type
+is always trivially seen by checking the file/line reported in the
+trace anyway.
