If it were to be changed, one could add a text-mode option in 3.7,
say "t" in the mode string, and a PendingDeprecationWarning for

"t" is already supported in open()'s mode argument [1] as a way to
explicitly request text mode, though it's essentially ignored right
now since text is the default anyway. So since the option is already
present, the only thing needed at this stage for your plan would be to
begin deprecating not using it.

Thanks for briefly de-lurking.
So then for PEP 540... use surrogateescape immediately for t mode.
Then, when the user encounters an encoding error, there would be three
solutions: switch to t mode, explicitly switch to surrogateescape, or
fix the locale.
