Behavioral changes to 'blame' should be designed concurrently with
changes to 'log', and probably 'status --show-updates' (and 'info'?).
Basically, to any API/command that carries a user name.
Once "how it's supposed to work" is defined, these changes can be
implemented incrementally (though, once you've got the functionality
for one command, it should be very easy to roll it out to others!).

Not to my knowledge.

Let's start by zeroing in on a really solid definition how this is
supposed to work. I'd volunteer to roll that into the func spec,
while you're working on implementing it for the 'log' or 'blame'
A few points to consider:
- We should be able to get both the user name of the original
committer and/or the user name of the actual committer. (The
requirement needs to be reworded to reflect this.)
- Should We provide an API/command-line switch for which names to
show, rather than always showing both user names? I tend to think so.
How would this (new?) switch interact with --verbose (e.g. for 'log')?
- If we only show one user name at a time, should it default to the
current behavior of showing the actual committer's name, or the
behavior suggested by the requirment of showing the original
committer's name? I tend to think the former, to maintain backwards
