It's probably because us'll don't believe that RTS is the best way to go. Sometimes systems sound worse instead of better if components are tightly clamped. Plus it's ugly and could potentially mar a component's finish.
In my personal experience I've had great luck using different types of footers to achieve the sonic differences I'm looking for... and the particular footers I use are not real expensive. They actually don't need to be expensive to work well and what footer works well for one component might not be the best choice for the next one.
I'm glad you like your rack but as you know, as with most things, it's different strokes for different folks and there is almost always more than one way to achieve a disired result.
