No, it should be as it is now.  It also applies when display is
list-item, compact, table, etc.  Otherwise separate rules would
be needed for those cases.

Should it?  The rule as originally written, when combined with the
rules in 17.2.1, handes this case already.  Some have argued that
that handling is not ideal, but that's a serious discussion.

That wouldn't be backwards compatible.  It might not have been a bad
idea originally (for non-replaced elements only), but now that existing
specs say such floats should be made as narrow as possible, it should
probably stay that way.

The width 0 can be turned into the browser-specific min-width.  (Not
that that's always what's done.)
