You're writting "Changes have been made", but I did not see any up to
this point in the series.

We write patch series so that they are bisectable, i.e. each commit
should be correct (compileable, pass tests, consistent
documentation, ...). Here, it seems you are introducing a breakage to
repair it later.

Other that bisectability, this makes review harder: at this point the
reader knows it's broken, guesses that it will be repaired later, but
does not know in which patch.
