That old repair shop owner made me question my whole approach to blown capacitors

Stopped by this tiny shop in Akron last week to grab a part, and the guy behind the counter, must be 70, asked what I was fixing. Told him it was a flash unit with a swollen cap. He shook his head and said 'you kids replace em, we used to just fix the charging circuit and leave the cap alone if it still held charge.' Then he showed me a stack of cameras from the 80s he still services without swapping a single electrolytic. It hit different because I've spent 5 years just shotgun replacing any cap that looks off. His logic was that most failures come from the oscillator or rectifier stressing the cap, not the cap itself dying. He charges $40 less per job than me and his stuff lasts longer. I tried his method on a 1982 Canon AE-1 program with a bad charge light last weekend. Turns out the transistor was the issue, cap was fine. Never checked that before. Who else has switched from routine part swaps to actual circuit diagnostics? How do you decide when to trust a 40 year old cap?
