It would accomplish somewhat similar goals as route-distinguisher, true.  And, having been used in that fashion would mostly revert to a prior ORF proposal:
https://datatracker.ietf.org/doc/html/draft-chen-bgp-ext-community-orf-02 <https://datatracker.ietf.org/doc/html/draft-chen-bgp-ext-community-orf-02>

That ORF procedure was replaced by rt-constrain for various reasons that have turned out well for us.  But the ORF in this case was in the "send me this" sense rather than "don't send me this".

For many deployments, there's only a single CE instance within a VRF.  In such cases, the case of site-of-origin becomes indistinguishable from the route-distinguisher case.
