I just stumbled across somebody else making the same point: https://bitcointalk.org/index.php?topic=289795.msg7796974#msg7796974 …

@ not same point.
@indutny was saying that if bitcoin used SHA1 we would've been migrated off by now. -
My point was that I see no evidence that they are planning cryptographic migrations ...
-
which I think is the take time, especially in an ecosystem.
-
I understand that being a few bits of weaker and a lacking some desirable properties does not mean K1 is broken.
-
with SHA-1 we had a better alternative for quite a long time. What is it for secp256k1?
-
not the point, the point is if they have no plan or infrastructure for one, ...
-
Bitcoin is too political to "just" add an algorithm agility mechanism b/c different algorithms benefit different factions.
-
However, I do think it is a good idea to add a mechanism to prepare for a needed change, if politics can be overcome.
