Obviously it can't be linear forever, if you assume the crack is along a circumference then eventually there will only be a tiny piece of metal still intact between the two halves, and one would expect it to fail far before then.
These kinds of failures tend to be linear until they are not, and the failure mode is catastrophic. If I were in charge I would have already shut off that module on the risk/benefit analysis of catastrophic loss of the station vs. not being able to evacuate as quickly in a less catastrophic emergency. Maybe they are worried they won't be able to get the hatch open again if they can't equalize the pressure again?
For historical reference, consider Aloha Airlines Flight 243[1].

Well note that they currently keep the hatch to the docking port closed unless they're using it, so that presumably mitigates some of the risk (assuming the leak is confined to that location). Not using the whole Zvezda module itself would be more or less impossible from my understanding. If they decided to stop using that dock port at all then I think that complicates planning and makes everything overall riskier, so while it wouldn't be a disaster to do there's still risk you have to weigh.
