I don't see any advantages of that!
I introduced this feature when I found gross performance problems in some of our models; at the time it was radio masts. Some of the problems come from the way they were modeled, others from inefficiencies in the .ac format itself. I wrote a program to run the OSG optimizer, as well as some of my own optimizations, and write out the model in the .osg format. I'm sure you agree that it is not efficient to do this at scenery load time while running FG. The model names are embedded in the scenery, so it's not practical to change them without rebuilding the scenery, AFIAK. Hence, this substitution mechanism. The only problem I see is picking up files from unexpected places, which really means the OSG sample data directory. I didn't really see picking up the wrong cow model as a deal breaker :) But I'm willing to change this scheme if it's really too onerous. Would picking another file extension for the substitution, such as ".fgm", satisfy you?
