> Any unexpected entry into safemode would require a report, multiple meetings with the customer, and them being pretty angry. Their line of reasoning seems to be "Safemode->Something is wrong->Why is something wrong? We're not paying you to be wrong". I'm personally of the opinion that safemode isn't that bad. It's fully recoverable and shows the system is working properly.

To the last part first: Good that safe mode kicked in and did the right thing, but now what? What caused it to enter safe mode in the first place?

That's why they care when it happens. If they don't know why it's entering safe mode, they can't correct the actual problems in the system.
