Yes but flying VFR into Meigs was quite common, which was not for Tegel.
The Gaya Tegel is representing an airport like it was, when it still existed, incl. static aircraft, approach lights etc. So IMO also the navdata of this past time has to be included.
If I had bought Tegel (which I haven't) I also would have expected to have applicable (retro) navdata included. Otherwise the purchase of such an airport really does not make much sense. It is actually not much work for a developer to include obsolete navdata in his product. Kai Tak has got it.
All the promo pics and the video on the Orbx product site arouse the impression that this is a fully operational airport of the past.
