Super thin margin stuff like space flight only "works" because they cross their Ts and dot their Is. There's probably no danger here, the repairs will probably go fine and be uneventful, but you gotta treat every situation like it's the real deal because otherwise it'll get you when it does happen.

Agree to precautionary principle. Disagree to certainty of fixing because this is a long standing leak which just doubled in intensity: either it got bigger, or there are more. Either way, we have no reason to be optimistic a bigger leak problem has a faster MTTR or even triage.

Who is the "they" in your post? The ISS is a bit interesting because its a cooperation between NASA and Roscosmos.
