Yes, but with floats they mean today's existing inline floats. Those behave
like they do for historic reasons. But when we create something entirely
new that will behave differently than inline floats anyway, I agree with
Rossen, that there is no point in recreating what Exclusions already do.

Exclusions seem to provide us with everything we need. Authors who know
exclusions will be able to handle page floats with ease, instead of havign
to learn entirely new new strategies to make certain things happen (such as
doing "wrap-flow: clear" ).

Well, yes we use the property name. And that's why I have been thinking
that maybe we should not do that. However, the feedback so far from other
people in and around the CSSWG has been to keep the name and with that the
property.

Inline floats continue to be as they are. I don't think anyone is planning
on touching them. Page floats are a slightly different animal. Then there
is the third thing which has come up a few times which is basically "page
floats that float into the four corners of a non-fragmenting block element".

I am not sure I can follow you there. Exclusions that the user places
manually that are not page floats are not affected by page float placement,
as far as I know.
