Comment (by karsten):

 Let's only do this if the changes are really small. It would be really bad
 to spend too much time on CollecTor so that we won't have enough time left
 for the other releases.

 Do you want to write a patch that does what you suggest, and I continue
 preparing and testing the other patches? And if it turns out to be harder
 than expected, we save this additional step for later?

 (By the way, CollecTor also uses a JSON formatter/parser for the reference
 checker in its relay descriptors module. That means, even if we use
 metrics-lib classes for `index.json` formatting ''and'' parsing, we'll
 still have unrelated JSON code in CollecTor.)
