Does anyone think that a validity lifetime should be associated to the

Absolutely.
I agree - but with a slight clarification: the delegator associates an "expiration time" with the delegated prefix, which defines the time after which the requestor can't use the delegated prefix. The requestor then chooses preferred and valid lifetimes (presumably not greater than the expiration time on the delegated prefix) for the prefix.

I think the requestor should be able to choose lifetimes that are shorter than the delegation duration from the delegator, and using a different term like "expiration time" would be clarifying.

Indeed RAs sent on a link associate a valid lifetime and a preferred
lifetime to the advertised prefixes.
If your prefix is delegated to you, the delegating entity has to
provide a lifetime in order for the requestor to build meaningful
RAs.
