Thinking about this a bit . . . I'm not concerned as long as the filter remains intact during its use and doesn't crack or break while in use. I'm used to oil filter media in self-contained oil filters being flexible. But, in our application, the filter media is not glued to plates on either end and would need to retain its shape during use (i.e. not get squishy or soft). Thus, an oil filter cracking / breaking (only) during removal from the canister is something I've not experienced, but probably not a problem.
