'Hardcore mode' is already a thing, just login as 'Administrator' (SID 500) and run a script to shutoff all the bullshit protections (Group Policy and PowerShell debloat script)
As much as these solutions sound good a true fix requires a drastic change in corporate culture at Microsoft and an attitude shift towards their users which seems ... extremely unlikely to happen in the mildest words. No "hardcore mode" or transparency about telemetry, or removing any other anti-user behavior will last as long as the people who made these decisions and the culture that led to them stay in place.
