This is from a year ago:
It looks like they don’t have multisig, so B&C cannot support MAID. That was a year ago though, I don’t know about now.
Getting shareholders to vote for MAID is another story entirely. I don’t know any reason why it would be considered a high priority item compared to implementing the basic coins like BTC, NBT, BKS, and BKC that are required for B&C functionality.
