[Python-ideas] keywords and backward compatibility

There seems to be a recurring theme of ideas wanting a new keyword but not being able to have one because of backwards compatibility. What if I have a way to ask for the new keyword? Would that make it easier to accept and implement some of the new ideas? The "given" keyword for example could be allow with a statement like: from __future__ import keyword_given If this method of extending the python language was used for a while I can see that the downside would be that an author of a new module will end up potentially putting a lot of from __future__ statements as a preamble.
