### $PSNativeCommandUseErrorActionPreference

The `$PSNativeCommandErrorAction` preference variable will be implemented as a boolean.
The `$PSNativeCommandUseErrorActionPreference` preference variable will be implemented as a boolean.

- When enabled (1), `$ErrorActionPreference` will affect native commands with described behavior.

Making this name longer seems like the wrong direction to go. Also, if it ends in ActionPreference then I would expect it to be of type [System.Management.Automation.ActionPreference] instead of [bool].

I agree that the variable being boolean and the name ending with Preference sounds weird. The name is so long that Use gets lost while reading. PSNativeCommandErrorActionEnabled, PSEnableNativeCommandErrorAction may better highlight the implicit type of the variable. Still they are long names, though.

of the PowerShell cmdlets is handled separately with `$ErrorActionPreference`.
