Looks like Neil Gaiman pretty much confirms the theory that the Eleventh Doctor era Cybermen are a result of an alliance between the Mondasian and Cybus Cybermen.

"They met a bunch of the Mondasian/Telosian Cybermen, and there was some cross-breeding and interchange of technology, which is why you then get the ones that look like, but actually aren’t, the Cybus Cybermen."

Which is what at least some editors supported from their first appearance. While we should wait with actually stating it as a fact until it is confirmed in-universe, I think that this statement from Gaiman should be enough for them not to be lumped simply under Mondasian without any explanation, especially given that they do look like Cybus Cybermen visually, so this fact should at least be noted.
