You are giving these two options already:
- The former works for all Python versions. Although it may appear
  tedious to convert existing code to replace all Unicode literals
  with function calls, it would actually be possible/easy to write
  an automatic converter that does so for a complete code base,
  based on lib2to3.
- the second version is truly practical for all applications/libraries
  that only support 2.6+.

In addition, there also is another option:
- use 2to3, in some form

So you have already three solutions which are all transitional in some
sense, and you want yet another option? I fail to see why this option
is more practical than the options that are already there.
