True, I would not, because there would be no reason to. I would never use the big-big combo, ever. Nor the small-small. That is called cross-chaining and I believe it doesn't work well even if the chain is sized correctly because the chain line is too crooked, especially on a smaller frame with short chainstays, such as my bike. The big and small rings would basically be 2 extra speeds on top of a 1x10 drivetrain. Equivalent to a 12-speed cassette with a 80 tooth climbing/towing cog and a 7-tooth speed cog.
Idk I have a feeling that is SRAM announced a 7-50+ cassette, the 1x folks would trip over eachother trying to throw money at it
