Yes, Aaron has (also) designed one, of which he wrote in August:

It's also possible to do append-only weaves.  Trivially, you can just
store the weave itself in a revfile.  I have also done some work on a
natively append-only weave format; you can see my work-so-far here:

So I'm comfortable going with weaves for now since
1. latency trumps throughput most of the time, and weaves are only
somewhat larger than the original files
2. we can do append-only weaves later, if we think it's valuable.
----------

I agree that the robustness of an append-only format is nice, but I
want to get some experience with this basic format while we work on a
more advanced one.
