Special case exclusive toggles?
Perhaps we could special case rows of exclusive option toggles from generic linked buttons, and have a more obvious styling along the lines of switches rather than buttons, e.g. like this:
![image](data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==)
This would also help make it more obvious which button is active when there's only two.
