Yeah, for this patch series I think it's mostly a lack of interest.
Which is too bad, because it does address some real issues with
git-fast-import(1). Part of the problem is also that this area does not
really have an area expert at all -- if you git-shortlog(1) for example
"builtin/fast-import.c" for the last year you will see that it didn't
get much attention at all.

Anyway, I'm currently trying to make it a habit to pick up and review
random patch series that didn't get any attention at all every once in a
while, which is also why I reviewed your first version. I'm taking these
a bit slower though, also in the hope that some initial discussion may
motivate others to chime in, as well. Which may explain why I didn't yet
review your v2.

In any case I do have it in my backlog and will get to it somewhen this
week.

Agreed. Especially given that this is your first contribution, the
quality of your patch series is quite high. So I don't see much of a
reason to hold back the other patch series in case they are unrelated.
