All the nice interior maps people have put effort into over the years will be lost?! That sucks. If you could do what Dimirty said I would like this, but maps like GTT Viano, Southhampton, downtown, all the maps people have spent so much time on will be lost to even the people who still want them. Can't there be some sorta switch for the graphics?
Check the RTB stats, very few people make maps. And the tools + process for making maps is bad, so it's very hard to make good ones. It's better to focus efforts on beautiful bricks and great builds. Having support for interiors at all is a huge pain, so we won't do it. -- kompressor
