No. I'll try to deal with it today. My brain was working at half capacity yesterday and is today, because of a cold.

Deal with deprecation first. If I get completely run down by the cold, worst case scenario is I'll at least try to develop the battle plan for t-f beamformers. I'll update the google drive doc once I have any plans ready and will open a PR as soon as I have any code.
