FRRouting supports using IP network address as BGP peer instead of explicit configuration each of them (bgp listen range option - http://docs.frrouting.org/en/latest/bgp.html#clicmd-[no]bgplistenrange%3CA.B.C.D/M|X:X::X:X/M%3Epeer-groupPGNAME).
We could this to VyOS to extend BGP functionality.

I tried adding it but failed miserably. This should best be done with the entire BGP rewrite.
Here is my change for future reference:
