Change their implementations to check full object equality, with case insensitivity for filename strings.
The filename case insensitivity doesn't extend to filenames in condition strings, as conditions are compared as strings, but the risk of duplicates due to that is much less than the risk of treating non-duplicate objects as duplicates.
Rewrite it as reStructuredText so that it can be hosted alongside the
API documentation on Read The Docs, which allows linking to WIP syntax
documentation.
