.. putrefaction adds character.”
For steak it does.  If cutting out the sides of a steak, the exposed beef will have bacteria deposited on it leading to a degree of tenderization if stored right.  That’s one reason why steak is put on a sizzling hot grill .. not only to cook (“char”)  the meat but kill off any bacteria on each surface.
That’s why hamburgers aren’t recommended to be rare if the meat has been cut up for awhile.  All the bacteria get mixed in and they start growing into places the flame won’t reach.
Presumably it’s the same with chili.  Also freezing something like chili may send little ice shards through the various tomato pieces and other plant cells .. resulting in a mushy flavor when thawed.
That said, the only person I knew who’d take steaks out to grill (assuming a grill and fire conditions allow it) packed in one of those frozen steaks individually wrapped and vacuum sealed – probably for blood not to go everywhere, temperatures to control bacterial growth, etc..
Food poisoning out in the wild is zero fun when a hiker could probably get just as good chili from Mountain House (in the form of chili mac  .. a US Army “favorite”!).
(of course I shouldn’t be giving any culinary advice as I’m about to order a “keto burrito” from Pollo Loco .. aka Crazy Chicken).
