If these were arbitrary keywords invented purely for CSS, it would be somewhat more acceptable, but pt, pc, in, cm, mm are long-established real-world units with well-known relationships in designers' minds, and it seems fundamentally wrong to redefine them in CSS in such a way as to break that model.

Not every web designer is a web-only designer. Some may have a background in print design, for example, in which case they're likely to have a pretty clear idea of the relative sizes of "pt" and "in" or "cm", and they're entitled to have that relationship maintained in the CSS world (I think).

Web-centric designers who never use any of these will of course be unaffected by any redefinition of them anyway, so we needn't worry too much about them in this context.
