Normally, enhancements are not backported anywhere.  New API == new 
version of Python.  You can, and people and organizations do, compile 
your own customized version.

Official (pydev) bugfixes for 2.7 end 1 Jan 2020.  Many projects have 
already stopped or will stop before then  fixing 2.7 versions of their 
packages.  But some people will probably use it for at least another 
decade.  Do what is best for you.
