Yes, that would be nice.

I just did a very simple test: I deleted all the .elc files and then
said `C-x v g' on a file and got the familiar "invalid byte code"
message.  At least in this instance it would be more helpful to say that
the .elc file no longer exists...  or perhaps not backtrace at all, but
just load .el file?

Debugger entered--Lisp error: (error "Invalid byte code in 
/home/larsi/src/emacs/trunk/lisp/emacs-lisp/cl-macs.elc")
