 What about always using both types of DS record?  Why does everyone
 publish both SHA-1 and SHA-256 digests?  RFC 4509 is more than 6

=> in fact perhaps it is the right time to jump to SHA-256 only?

One data point: of 89 TLDs with DS records in the root zone,

 5 use type 1 (SHA-1) only   [they are BR, MM, NA, PR, TH]
47 use both types 1 and 2
37 use type 2 (SHA-256) only
