A CWT font with no rootstring has fairly clear implementation obligations.

An EOT font with a rootstring has murky enforcement obligations.

A CWT font that is allowed to contain a rootstring in the binary padding seems like the worst of both worlds, and I would not like to stand up in court and defend either the design, or have a jury try to  divine the font creators' intentions, from that case.
