Ok, I can see that.

I guess that, using the W3C jargon, this is something that could become clearer at a later phase when a larger audience begin to look at this stuff and experiment with it. At the moment, we are all talking about 'feeling', good or bad, about this, which is subjective anyway.

Ie, I am fine switching this if the majority of the group thinks it is better, but we should definitely keep an eye on this and maybe flag as a specific issue that the group would like to have a feedback on.
