For the reaction of 2-butyne with water, is there an intermediate unstable step of 2-buten-2-ol before it becomes a stable form of butanone?

Because I know that there is an unstable intermediate step for the combination of ethyne and water, but I wasn’t sure if it was the same rule for all alkynes.

Thanks!

(and yes, there are several intermediates, and even the final product - being an enol - can tautomerize)
