Incremental version numbers have proven very useful in many scenarios. I'd be careful to list the lack of support as a feature for git.
I know that support can be hacky at best in a DVCS but often, especially in the common "semi-centralized" workflow, that's good enough. Don't underestimate the communication benefits of being able to talk about specific revisions in chronological context, in plain english. "That was fixed in 982" is much easier to parse and congest for a human than "That was fixed in d934c8" or "That was fixed on last Tuesday".
