My first thought here is "Can you link to any evidence for that, or must we just take your word for it?".  Regardless of that, adding things to OSM that _literally do not exist_ is NOT what OSM is for.

Plenty of options are there for enhancing OSM's "in reality" data with other things that you'd like to be there, and the place to start with that is surely the community forum, as I linked above.  If you ask there I can certainly help point to examples that combine OSM data with "imaginary" data, and update an OSM rendering database with external data directly.

To be clear we (OSM's Data Working Group) have received a complaint that this data doesn't really belong in OSM, and as far as I can see, it doesn't.  If you don't revert it; we will - but I'm sure that lots of people across OSM (including me) would be more than happy to help you achieve your goals.
Best Regards,
Andy Townsend, on behalf of OSM's Data Working Group
