802.11b was CCK modulation (and to a lessor extent PBCC, but that didn't take-off).
DSSS wasn't 802.11b, it was 802.11 (or half of it, the other PHY at that point was FHSS). 802.11b's 1Mbps and 2Mbps modes were DSSS, and pre-existed 802.11b. These (and the FHSS PHY) were all part of the 1997 standard. 802.11b and 802.11a came along in September of 1999.
Who is 'we'? Because you don't seem to know what you're talking about.

I'm one of the other authors. Maybe I'm wrong, in that the written history tells it differently, but I'm recalling what was said around the meeting table and across the office partition. I might be a bit loose with the terminology, but to me it's not packaged up neatly into standards, as it was a non-linear development process when I was dealing with it. --- Edit: fix URL + name
