ISP support for use of 4-byte ASNs in peering

Folks - 
 
  Is there a public list somewhere of service providers that do not support 4-byte 
  autonomous system numbers when peering?  (if not, should there be one?)

  At ARIN, we are still having parties returning 4-byte ASN's (seeking 2-byte instead),
  indicating that the 4-byte ones are not sufficiently accepted in peering to be usable.  
  This is obviously a less than desirable situation, and it appears that it is not trending 
  towards resolution at this time.

Thoughts?
