Actually never mind, in pure IP environment you'd still need
add-path/diverse-path feature to get the alternate ORR paths across to clients.
But actually the whole purpose of ORR was to distribute primary as well as
alternate/backup paths, but in an optimal way, as opposed to brute force *all
paths(Type1 RDs) or inefficient primary/backup paths(add-paths).
The Junos configuration actually allows for manual definition of primary and
backup virtual location.
(hoping for automatic and/or policy-based primary and best backup selection in
future).
*The number of paths advertised with this approach can actually be scaled down
with careful assignment of RDs among given set of AS-exits.

Looks like routing-instances is the difference. Within routing-instance
add-path does not complete for me too, neither on QFX nor on MX.

Thanks for checking, that's helpful!
In fact, I am using routing instances. Like you, I can get add-path
send/receive outside a routing instance, but inside, add-path is
hidden. I assumed this was independent of the routing instance
(configured type virtual-router), so I didn't bother to check that.
Does "set routing-instances rr1 protocols bgp group apath family inet

No ideas on what can be wrong with your configuration :(
We run add-path on most MXes without any problems. Just tried with QFX

Yes, it's accepted. But my goal is to get load balancing to a set of
hosts, not optimal path (all routes are equal in my setup). My
understanding of the above option is that it still selects only one
route.

Is the RR use in MPLS-VPNs environment or just pure L3-IPv4/6 environment?
If it's MPLS-VPNs environment, then you don't need add-path.
Also if ORR is supported on QFX by any chance you might want to try that
instead of add-path.
Does it take the below?
