Dear WG,

One last follow-up, I realized when updating the "progress-type"
enums that our plan to just have a "boot-image-success" was not
enough, because with boot images, there is the huge question of:

  was the boot image already installed, or was a new boot image
  installed and a reboot is eminent.

It matters because, in the latter case, the sequence to progress-
reports that bootstrap server is effectively ended, whereas they
more are expected in the former case.

This being the case, I'm thinking to exchange the single enum:

  boot-image-success

with the pair of enums:

  boot-image-already-installed
  boot-image-installed-reboot-eminent

and define that the device MUST send the latter if the case arises.
I'm open to less-verbose naming suggestions but, more importantly,
are there any objections to this proposal?  [I'll assume that this
is okay if no objections are raised.]

PS: once I post -23, so that the diffs can seen, I think the WG
    should be given one more chance to review the changes, before
    falling back to Mahesh to push the button.

PPS: I also received an early Security Directorate review that
     has some overlapping concerns (i.e. the error handling in
     Section 5.6), but also some other things (mostly Security
     Considerations).  I'll be sure to run any non-editorial
     changes past the WG as well, before also going into -23.

Thanks,
Kent // author
