I admittedly don't engage with the Haskell community much myself, but I'd speculate that part of the problem is the fact that C++/Java/Python/etc-style exceptions (as opposed to things like Either Excep t or SomeMonadFail t) are very boring implementation issues that specifically need to not get done. I'd also speculate that whoever you talked to did a poor job of articulating that.
