Thanks. Should I open a bug for it?
I ask because it seems that there might be three options:
True, False, OnlyIfDifferent.

The last option would be to keep the changeset the same where possible, but where not possible switch to including the extra convert_revision meta-data.

If I understand correctly, as of now, either all changesets will have the convert_revision meta-data and thus cannot have the same changeset hashs, or all changesets will not have the convert_revision meta-data and thus in cases where the changeset hashs aren't going to match, the meta-data is not going to be recorded.
