Comment (by Roland Haas):

Running all new (Proca) code shows only differences in post-merger, so this does seem to indeed be ok. I will try and spend a couple more runs to track down the first commit that introduces visible changes though based on @Peter Diener 's previous work it likely will be the one that recomputes eps from rho after reading in ID.

Zoom in to post-merger only:
