The only telemetry you get will be from users that are experiencing a severe problem who also have the technical know-how to turn it on. You will have no idea how prevalent the problem is amongst the general user base. There would be no way to prioritize debugging the issues.

There are other ways to test software... Especially the use-cases mostly used by users not well versed in the tech world.
