Very interesting question indeed,
and I believe it's valid requirement as well.

I'm just trying to find out, to no avail, if one can control what MAC addresses make it from MAC address table to MP-BGP and with what attributes.
If such a policy attachment point would exist one could tag MAC addresses with standard communities there (but I think no such thing exist in Junos or XR)

So when you tried to tag the MAC routes using iBGP peer export policy -has that worked please?
