Agreed. If it takes a week to make a line change it'd be very unusual IMHO if the entire team were not aware by that point of some the challenges involved. It may even warrant a short presentation on the technical challenges and how the issue was tracked down or solved; good learning opportunity.

On the other hand, if somebody is constantly disappearing for a week+ with a low complexity ticket, gives cagey standup updates, and then submits a PR that looks like it was thrown together in an hour.. That's a red flag that needs attention.
