What makes you think this is unmanageable? There are plenty of counter examples of existing facilities where this works.

To name the one I know best:

With ~10 of its ~170 systems delivered, ITER's system is above 1 million EPICS records.

More than 90% of contributions are in-kind, including their EPICS-driven control systems. After passing acceptance testing and integration, they're ours, with basically no support from original designers. 

This is manageable with a configuration database, a strictly enforced hierarchical naming convention and thorough integration procedures.
