Reconciling "cryptokey-based" and regular routing

I need to have multiple gateways on my WG network that can provide access to
the entire IPv4 (or IPv6) Internet, for redundancy and load-balancing

In WG terms this means I need to set AllowedIPs to on more than one
peer. Then I would add routes into the regular routing table for various

ip -4 route add via
ip -4 route add via


ip -4 route add default \
  nexthop via weight 1 \
  nexthop via weight 1

or whatever.

But as documentation and some testing show, this can't really work in WG's
"cryptokey-routing" system. If multiple hosts have as allowed IPs,
WG just sends everything to a random one of them (the first one?),
disregarding all of the routing table settings from the examples above.

Is there any possibility to still use multiple routers like that?

If not, then could you add an option to not use AllowedIPs for routing?
Or at least to not enforce filtering on incoming packets -- then perhaps I
could have only and in AllowedIPs for those hosts, and
outgoing routing would work properly, with replies from Internet hosts not
getting filtered out?

(Apologies for multiple posts per day, I'm just deploying WireGuard for the
first time today, and it's quite unusual compared to what I used before. I
will stop soon :)

With respect,
