Yes, I was very much against it but have warmed up to the idea. We certainly considered the alternative of having a separate ButtonBlock/SegmentedButton element and a different abstract construct for Radio/CheckBox but in the end the simplicity of ButtonRow and ButtonColumn won out. It looks declarative by nature and fits well with existing concepts like Row and Column.
One part of the existing API we did not like was the groupType: "None/One/Many" as the names were confusing and would essentially override checkable and checked properties on the contained buttons. Instead we simplified it to "bool exclusive", meaning the checked property is exclusive on all items contained within it. If it is disabled, you can set those properties on the contained buttons as you please. This also solves some logical inconsistencies, since for instance there is no optional checkable property on a CheckButton, but Button has it. There is one thing with the existing implementation that is still open for debate though, and that is that the button only reacts to "clicked", meaning you have to press and depress a button for the exlusive selection to change, where in certain cases you might expect it to instantly change on press. I am not sure if this is something we want to dictate at the API level, or leave up to the implementation yet.
