Don't call me Chicken Little -- the sky's not falling, but . . .
Habitually pushing current through an almost-dead battery will shorten the alternator's life, could kill it outright. Alternators aren't designed to charge a dead battery, just top one up after a normal start. This is why you won't find me offering anyone a jump start. Use my charger . . .
Waiting until the battery actually gets bad enough to die might be penny-wise, pound-foolish given the cost of the alternator, the struggle to replace it, and just the darned inconvenience of getting stranded somewhere.
I vote for prophylactic battery replacement every 3 years, or buy an electrolyte tester so you can monitor the battery's decline. The EL section of your factory repair book is very specific about when to pack it in.
According to the book, the OEM battery was rated at 80AH. I don't know if your can derive CCA from that.
