Deprecate/remove fix-encoding-pragma hook?

[mxr]

Since py2 is long unsupported

[asottile]

I think yeah, or at least make the default behavior to remove it -- or perhaps recommend pyupgrade instead

[mxr]

Suggesting pyupgrade makes sense to me. So to be clear the hook would no-op and fire a DeprecationWarning which suggests pyupgrade?

[asottile]

probably a minor release which prints a warning to stderr and adding (deprecated) to the hook name

and then in 6 months a major which deletes it (autoupdate handles this nicely)
