pbr also supports "environment markers" which we would want to preserve when round-tripping (reading in,

I'm assuming you didn't follow the "conditional dependencies" link from the description in that first paragraph, as it would have taken you to the corresponding section of one:
https://www.python.org/dev/peps/pep-0426/#environment-markers
You should probably also see:
https://www.python.org/dev/peps/pep-0496/ https://www.python.org/dev/peps/pep-0508/#environment-markers
Quickly skimming relevant changelogs, environment markers have been supported by Setuptools since 0.7, and directly in requirements lists since pip 6.0.
So we still need InstallRequirement.to_requirement_str() as described above ? Is there an implementation which does not mangle hashes and/or environment markers when *writing out* requirements.txt; so that --save could be implemented?
