Re: 7-day CfC: notes on option, treeitem, and spinbutton about children presentational - closes 15 June

Sorry I'm a couple days late responding to this. 

Concerns with making "spinbutton" children presentational:
I don't think spinbutton's children should be presentational until there is a solution for the ARIA's coverage gap wrt operability. As an example, there is no good way to make custom sliders accessible on touch screen devices because there is no way to trigger the increment/decrement events other than through de facto keypress events (this workaround is not sustainable or recommended for touch screen interfaces). If the WG makes spinbutton's children presentational, the same problem will apply. Author's are currently able to make spinbuttons accessible by using descendant stepper buttons that are individually operable. (Note: The native stepper buttons on macOS and in WebKit are implemented this way.)
