	This seems to be the case the more we think through this.

	Or simply multiple versions of the same modules at the same time. ODL lets you do this, for example, and happily works.  But the other more IETF-related situation is as you say, if there are two draft models for the same features.  One could and should 
be able to run them together, for at least experimental purposes. 

> I have no issues with there existing modules with overlapping concerns, even when implemented simultaneously by the same server.  I'm projecting, but it seems that the uber tree approach would put a freeze to such experimentation, which is fine for a specific project to hoist onto itself, but seems inappropriate for a standards organization.  Again, I like the idea of relocatable modules, as it seems to allow coexistence of both options.

	I agree.
