Feature or enhancement

Thetyping module has a huge API, and new features continue to be added in each version of Python. Deprecations should be done carefully and slowly, to minimise disruption for users, but we should nonetheless aim to shrink the API where features are no longer needed, so as to make the sheer size of the module less overwhelming for newcomers to Python typing.

Python 2.7 is now end-of-life, sotyping.Text has no use anymore (its sole purpose was to provide backwards compatibility with Python 2). I propose that we should now deprecatetyping.Text, with a view to eventually removing it.
