I have no pity for people doing that; RIPv2 has been out for a long, long
time, and RIPv1 was the last reasonable excuse for doing things that way.
There are few reasons, other than the intentional waste (or hoarding) of
addresses, to assign more than a /30 to a PTP link. Unfortunately, many
vendors are still clueless about /31s, or I'd revise that statement even

There are legitimate technical reasons for not using unnumbered.

Perhaps there are technical reasons you're not privvy to; perhaps it's waste
or hoarding. Either way, it's close enough for us to not quibble over
here -- though presumably ARIN staff would require a justification for such
when their next request comes in.
If you want to talk about waste, look at the folks with a /8 (or two) who
could likely fit into a handful of /16s, or the folks with dozens of /16s
who only use a single /24 outside of 10/8.

I've seen plenty of horrifying examples, though NDAs prevent me from naming
names. However, I know better than to think that all, or even the majority
of, legacy holders deserved to be tarred with that brush; many have been
quite willing to voluntarily return space they don't need. So far, just
asking politely has netted ARIN quite a number of returned blocks -- and
threats have, so far, netted the community nothing but a bunch of animosity
and/or fear. I'm in favor of what gets us the most productive results for
the least effort. Making enemies of people we want something from is not
helpful on either front.
