The simple subdivision as a type only causes issues like no-continuous normals across edges, inability to reliably switch the type and things like this. The new subdivision operators supports wider variety of how to add details to the model, which are more powerful than a single one-time decision on the subdivision type. The versioning code is adjusting topology converter to specify all edges as infinitely sharp. The reason for this (instead of using settings.is_simple) is because in a longer term the simple subdivision will be removed from Subsurf modifier as well, and will be replaced with more efficient bmesh-based modifier. This is finished up version of D8436. Differential Revision: https://developer.blender.org/D9350
