Since watermarking can be present on any audible signal, that means you can say LP supports audible watermarking. However, we know that realistically its not the case. Same with SACD.Thing is, with SACD Sony specifically designed it to be resilient without watermarking, its not part of the recommended specification, never was. It is the absoloute opposite for DVD-A, where until the last minute watermarking was compulsory and every player had to detect it, every disk had to include it. We know that every SACD doesn't had watermarking and that nearly every DVD-A title does (except for audiophile labels). So their is no need to debate this, the proof is in the pudding.
Finally, with regards to mandated stereo, if its compulsory, at least they'll have to include it. Given the fact that nearly every recording engineer understands the value of music and quality, chances are they will always include a quality mix. The Beancounters can't stop it being included. With DVD-A, Mr Beancounter can just say "We use MixDown, a valid part of the DVD-A specification for legacy 2-channel systems". For all historical recordings, there will always be a 2-channel mix in some format for them to include. For new recordings, well Stereo becomes less important, since they can be recorded well in 5.1 if that is what is intended. Still, if they are forced with a decision to appeal to mass market, they can always ensure the stereo mix is sorted for audiophiles. Mandated stereo always encourages them to do the right thing.

Follow Ups:
The watermarking is added as an option to the spec on request by the record labels representatives.Eventually they will use it for sacd as well.
They havn't so far.... rememeber, SACD can't be recorded at home and is a protected media. Now your grasping at straws.
It's a logical assumption.Philips demonstrated watermarking technology so it's there.
There are additional 'features' possible with watermarking.
-Tracking pre-release copy's leaking out of studio's.
-Royalty gathering from airplay.
-Control over (future) digital recording devices that read the
watermark.
You may be right in the future, it is a valid path for things to take. However, its not the case at the moment, which is the important thing.
