When I said it is not a problem, I meant there is no burning, systemic
problem with the backend as there have been in other backends.

However, we are burning plenty of time of engineers supporting it for every
change to the common code generator. Also, we have known bugs in the code
and the backend, and no one to really report them to. This doesn't seem
like a healthy state for a backend to be in, and it also doesn't seem like
a new state. (again, I've not seen any real activity here in all of 2012...)
