If the ability to specify 'auto' in iproute2 isn't an absolute requirement
and iproute2 upstream rejects the idea then implementing this in ifupdown*
would also be possible.

I maintain ifupdown-ng in Debian (and am involved upstream) which already
has rudimentary [VRF support] I'd be happy to help you work on this, but
the first step really is to ask the iproute2 maintainer,
Stephen Hemminger <stephen@networkplumber.org>, to consider this feature.

[VRF support]: https://github.com/ifupdown-ng/ifupdown-ng/blob/main/executor-scripts/linux/vrf

Please CC me and the netdev mailinglist: netdev@vger.kernel.org and be sure
to include "iproute2" in the mail subject. That list serves many projects :)

I'd also recommend trimming your feature request down to the essentials of
what affects iproute2, kernel maintainers are busy people. Don't waste
their attention. I can help you draft something if you want.
