Hmm, it DOES have a clear definition! I wasn't familiar with this one, but obviously it's out there; it appears to be more common in Germany and France. Okay, it has utility and a clear definition, so let's keep it. I'll include a definition for those who've never heard of it.

Dropped. Great!

Looks like cwt and lcwt are their official abbreviations.
Should we include this? Just the official symbols, or the older OOo symbols too?

Aka a "long ton". "lton" seems to be used too. Okay, now I know what it is... do we want to include it in the spec?

Yes, completely agree.

Okay, let's just call it "modern". I need an adjective to distinguish it from the traditional meaning of this measurement.

Okay.

True, I wasn't sure we wanted to add that. I fear adding much more.
