You say that like it's a bad thing.

The ARIN NRPM definition of Multihomed includes "has one or more routing prefixes announced by at least two of its upstream ISPs."  Are you really going to announce your prefix[es] to both your real provider _and_ your ridiculously low bandwidth provider?  Even if you prepend the latter considerably, you're likely to receive some traffic via that path.

If you have a GRE tunnel to each of 2 ISPs and announce your route over BGP to them, or, have some other configuration with them and they both announce your prefix to the rest of the world, that meets the ARIN test. The rest is an issue for the network administrator and not a matter for ARIN policy.

ARIN policy does not require your network to be functional or even useful. It's up to each administrator to decide how they want to operate their network and what level of dysfunction/lost packets they consider acceptable.

I would oppose such a policy change. I believe it is out of scope for ARIN's mission of address administration.
