The main problem there is that it runs like a dog and thrashes when you have big solutions and get near to 2GB of RAM usage. It's pretty silly on workstations that have 16-32 GB of total memory available. When they first justified the decision not to move to 64-bit a decade ago, it was more defensible, but time has moved on hard, and they've been fighting that decision, moving bits and pieces out of process ever since.
