In addition to that I find it very hard for us "external" modders to decide which level of detail on our own objects is suitable for Lotus.
This is also hard to decide for everyone. As some of us "internal" modders have already made some bad decisions, which led to performance issues, we want to prevent others from making such experiences on their own. The decision making is also very complicated, so I can tell you some factors:
- freeware / payware: When creating payware you should make sure, that every LOTUS user can play your add-on, it is not mandatory for freeware.
- size of the map: Disk space is no problem at all until you get to the point, where small maps have 5 GB.
- Does polygons matter?: Not at all, unless they are baked into the terrain. In this case the limiting factor is the map size.
- How often do they occur?: The standard setting for sleepers are 60 cm between two of them. A holder is placed every seventh sleeper. If you have a sleeper with 80 polygons and a holder with 80 polygons, what's worse?
In fact the sleepers and the holders are not quite equal compared to each other. I still would reduce polygons on sleepers, meanwhile I've got no problem with the third rail having the doubled amount of polygons.
