The develop folder is the folder for development eggs. If versions
forces to use other eggs, then it doesn't make sense to me.

In general I trust on what you are doing, but I'm not always 
sure what the real motivation is behind the concept ;-)
Probably there is a reason which I don't know about.

What do you mean by:

"develop eggs are also used for many system package installs :("

Only for development, it doesn't make sense this duplicated 
definition. It sound like a additionl seatbelt. For what is this
double definition good for? Or is this based on some implementation
details?
