I can't guarantee that your phone won't do the same thing tomorrow, however I did try that form despite having my battery (or rather, the whole top case) recently replaced - not for an expanding battery (as far as I could tell), but faulty battery life nonetheless. I got the same message that you got.

Maybe think of it in terms of aeroplane engines - do you go for the latest and greatest, or the tried and tested? How can you be sure that a replacement battery won't be worse after x weeks?

OP isn't asking for a guarantee. S/he is asking to know whether s/he has a device that is known to be at higher risk, or if s/he has an unaffected device.

You are responding to a straw man of "I want a guarantee that my device will never fail"

I was responding to "...what hope is there to guarantee that my computer will not explode in front of my face while I am working?". I'm struggling to see how it's a straw man argument but very well, I'll accept it. Contacting Apple is probably the only option now - we can't help.
