I do not. You can already use netlink to dump any table, I don't see any point
in making those available via /proc, it's not a precedent. We have a ton of other
(almost any) information already exported via netlink without any need for /proc,
there really is no argument to add this new support.

agreed. From a routing perspective /proc files are very limiting. You
really need to be using netlink and table dumps. iproute2 and kernel
infra exist to efficiently request the dump of a specific table. What is
missing beyond that?

On this, I realized now that without /proc the multicast caches can be
displayed using iproute2. But, it doesn't seem to have support to
display vifs. Is there a public domain command line utility that can
display vifs on non default table, i.e. the one that uses the support in
the kernel in commit 772c344dbb23 ("net: ipmr: add getlink support")?

Thanks.
