I believe that's mostly addressed in the cover letter [1].

  Patch #18 changes the logic of spi_uevent() to report an OF modalias
  if the device was registered using OF. But this patch is included in
  the series only as an RFC for illustration purposes since changing
  that without first applying all the other patches in this series, will
  break module autoloading for the drivers of devices registered using
  OF but that lacks an of_match_table. I'll repost patch #18 once all
  the patches in this series have landed.

IOW, it's labeled as such mostly for safety, since it has quite a few
distributed dependencies.
