Nick, I want to confirm with you that does T37 contribute to config
checksum computation?

You are correct.

At this point, mxt-save-after-loading-224sl.raw.xml contains identical
content to mxt-save-after-t9-83-write.xml (my previous backup). It looks
like the new configuration isn't being loaded correctly, or perhaps
configuration loading doesn't delete entries that are simply not in the new
configuration file?

Yeah, I would guess since T37 is not in the config, so whatever in the NVRAM
stays the same and when you --save its original value gets dumped.

Yes. You need to call --zero to get a truly blank config, before loading.
