[Standards] OMEMO Key Agreement

can you please describe the concrete benefits of your approach?
The only difference I can spot is that it's more implementation work for those that use libsignal (which at this point in time seems to be all implementations) and less for libsodium (which happens to not implement many other parts of the protocol as well and thus require a lot of work nonetheless).
I wouldn't use neither so I don't care about that part ;)
Is there any difference from a crypto perspective that I missed? As far as I can tell, this is only a constant factor for any attack I can imagine, if at all.

I may have a solution to our OMEMO key agreement discussion that satisfies all of us.
FYI, to get some more confidence in this approach, I prototyped it using both libsignal and libsodium:
The libsignal prototype actually mimics the 2 parts of libsignal that need to be patched; patching the library itself should be even less work/code (but I couldn't find an OMEMO client for my platform to apply the changes myself).
