These are factors which strongly go against TAPS being implemented in 
the standard library: it is novel and the usage of it is unproven, and 
it hasn't been standardized yet.

Generally speaking, the Python standard library only provides proven, 
standardized protocols. A few reasons for this:

- We don't have the resources of Apple, we can't support everything, 
  so we have to choose those which are most likely to be useful; 
  that means those with a proven track-record, not experimental or 
  novel protocols.

- We take backwards-compatibility seriously, so with a few exceptions,
  any API we offer would have to be stable. (There are ways around
  this, but we don't use them lightly.)

- The Python release cycle is relatively sedate and slow, and 
  experimental libraries usually need a much faster release cycle.


This is not to absolutely rule out a std lib implementation. If the 
networking experts among the core developers think this is a good idea, 
it could happen, regardless of how novel it is.

But in the meantime, I recommend that you consider writing a library and 
offering it on PyPI as a third-party library:

https://pypi.org/

If you are still keen to push for a standard library implementation, you 
will probably need to write a PEP:

https://www.python.org/dev/peps/

At the very least, reading over some successful PEPs will suggest what 
sort of arguments you should make in order to get TAPS approved.
