At the time the error message was written, there was only Thunk generation that was at risk of non-convergence so it made sense to write that at the time.

I think this is a good change to make.

Although I can't immediately see an easy way to do so other than optional trace messages, it may be worth some effort to invest in some way to figure out which of the various systems is having difficulty.

Please give MaskRay some time to see if he has any opinions.
