Why? Isn't that exactly what the past has taught us? That using one fixed fingerprint algo leads into all kinds of troubles? And not just from the engineering side (i.e. that applications simply take it for granted that the data will be SHA1, e.g. when parsing output of programs). Looking at other areas (e.g. SSH) tendency seems to be rather to support multiple fingerprint algos, and people can chose what they want. And from the crypto side, we also see how bad it was/is, to have fixed algos,... first with MD5 now with SHA1. It's simply naive to believe that current or future algos won't meet the same fate ultimately. > It is often useful to have a keyid to quickly (but insecure) refer to a > key.
