Does the data format matter for network communication? Are there
are some fields in changeset object that can not be easily provided
by Mercurial client? I mean it is not necessary to implement all the
field, only a small subset must be sufficient?

Do you mean that these people will object? =)

I had to rewrite my question completely, because it was considered too
broad. Well, it could be. Actually, the process of using Bazaar was
quite straightforward. Launchpad URLs for branch names are insane, and
I still don't know what I've done, but at least I've got the pull
request there -
https://code.launchpad.net/~techtonik/ubuntu-dev-tools/minor-python3-fix/+merge/247538

Was as simple as:
  bzr checkout
  bzr commit
  bzr push ...

In the end it is all "get the source, make a diff, store a diff,
upload the diff". Why there are so many problems with all this version
control? User identification is done over SSH. Revision number
assignment? Mapping revisions - is that it?
