implement `toMapText` and `fromMapText` as `unsafeCoerce`?

It appears that Key has the same Ord instance as Text so I wonder what would be the issue with speeding up these two functions by using unsafeCoerce

[Lysxia]

We can even keep it safe by just redefining KeyMap using Map Text

[MangoIV]

I mean it’s still safe, we’re just circumventing, for us, irrelevant roles. Surely though, just changing the key type would be good enough, if that was possible.
