I'm not so sure about this. The sites doing this today do not use @seamless,
and often want the content to fit in a fixed rectangle. Pushing them to use
@seamless has two significant potential downsides:

1) In the long term, if they do not actually desire the layout and styling
effects of @seamless, they will have to go out of their way to reverse them
simply to represent that their iframe is for partition purposes only and does
not have a designated purpose.

2) Currently no browser yet implements @seamless. If the validator started to
require either @seamless or @title, sites could start adding @seamless as a
voodoo talisman, without actually intending any effect other than to silence
the validator. If a significant number of sites start doing this, it will
poison the ability to really implement @seamless; the first browser to do so
would break the Web.

3) Sites could end up being pushed to add @title where it is inappropriate,
causing distracting and unhelpful tooltips in cases where the iframe is purely
an organizational device.

I am particularly concerned about point #2.
