Dood…. Coils last how long they last given a VARIETY of factors, including user error. For example I was using a super thin wire and accidentally turned my vape up WAY too high, and instantly torched it so hard, one area just burned in two, so that coil didn't have much longevity. I have also killed coils by dropping my mod and dislodging everything and it was just easier (for me) to recoil than try to fix that mess.
Often, thicker coils seem to hold up better after repeated use as well as some alien builds. I've had coils last me 3 or 4 months, with the proper care and cleaning.
As far as "discomfort with degradation of the coil" I would say that SHOULD and in fact CAN ONLY be up to the individual user, and really, I'd like to make that decision for MYSELF, not someone else, even if said someone else has a metallurgy degree (or not). I do, however, believe it to be a reasonable statement that over time a coil can degrade, and drop in performance with also a POSSIBLE leaching of metals but given the cost overall of coils, there is no reason to get all freaky about it. Just, treat it like dentistry. YOU KNOW when you are due a cleaning (whether you get one or not) but come on, you know. If you place a high value on ultra clean teeth and non elderly coils, well you change it.
However, I think it's a safe bet that you won't NEED to recoil THAT one on your trip although you may need to rewick it, but see points above as to how user error can happen and maybe bring one with you IN CASE you need it but in my opinion there is not, at this time any need for a PREEMPTIVE rewick.
Although if you'd like you can post a pic and we can all argue about it. Unless you already did that and that's what started the arguing, like, I can't remember.
I think you will be JUST FINE, and what YOU THINK about the situation is what matters .
