I'm not convinced this is a bug at all. It doesn't enable all airports either. Now railtypes are a special case in that you can use the newer railtypes with vehicles for other railtypes via the railtype compatibility, but I think a callback for the introduction date for railtypes is a better solution then mis-using this option.

Actually, it shouldn't make the airport window openable as it doesn't enable road/water depots/stations either. For (somewhat) consistency it should just make it possible to open all railtypes and road types that will eventually become available. So effectively it should "remove" elrail in tropic games from the rail dropdown as it isn't used there, or monorail when that's disabled by a NewGRF, or remove trams if there's not tram NewGRF loaded.

Ofcourse in all cases building stations/depots should remain as it is I'd say.

Allowing to build all railtypes is not intentional. They may come with speed advantages for present vehicles or whatever.

It is most consistent when this option is disabled.
