I totally agree, by phase 5 there will have been a process to delete all
non-ODbL data. The final stage of this will have to be an automatic "bot"
that is very conservative about what it accepts - so in your example will
revert to C's version. Just like with imports, we can do so much better if
there is a crowd-sourced manual process, rather than a dumb-bot approach.

I'm inclined towards this as the simplest, perhaps because I am not a
programmer who can contribute to the tools required to implement an
alternative. Downsides I can think of are that it breaks the history across
two objects and will also break external services that (despite advice not
to) use the object id to cross reference an OSM object. Are there any other
downsides I've missed?
This method could be used already, although it would be nice if editing
software could assist by providing a "copy and delete" function to create
the new object that could then be edited to remove the non-ODbL info.

As you say, this requires the final bot to be written to parse this, and
also anything that provides analysis of licence-status of objects also needs
to cope. That, to me, sounds like a lot of stake-holders who are all going
to have different ideas as to the exact formulation of the tag - this could
take a Long Time to implement.

Quite possibly, although I can't think of it!
