Not sure about that. IXP participants know where the route is coming
from, and why should it be of anyone else's concern whether I have a
direct peering with you, or use a RS for it?

Yes. BGP works by comparing AS path lengths, you know :-) - and that
would cause significant work as direct peerings would automatically
have shorter AS paths than via-route-server peerings.
Thus, traffic shift, which needs to compensated - like, by adding
extra prepends to direct peerings - which would have consequences for
the AS path lenghts seen by our customers.
In other words: we asked for AS-Path transparent RSes 15 years ago, and
this is still what we want today.
