So why not event driven rsync like mechanism between BGP_Adj_Ribs for
incremental updates ? *well for VPNs RTC would need to be mandatory*

Note that RPKI is rsync based which some suggest for BGP to relay on anyway ;)

Before you go there, you need to ask yourself if you want to continue
to have a protocol with incremental updates.  TCP is there precisely
to support that.

If you want to go back to periodic updates, then getting rid of TCP
seems much more credible.

But then the overhead become untenable.
