Generally I am still in favor of doing such a per-topic file split, in
whatever way exactly we proceed with CPU-as-a-device.

If this is supposed to go through my CPU queue then I would prefer to
move the [ehabkost: ...] lines chronologically between the Sobs fwiw.

What I would insist on is mentioning both new file names in the commit
message (qdev-core.h and qdev-properties.h iiuc) since the +++ stats are
ambiguous.

I spotted the following textual discrepancy:

"Individual" became "Indicidual" and the comment seems misplaced, which
makes myself ask whether this split was not done safely via copy&paste?
