Well, I wouldn't say it's a malpractice, but you certainly have to know what you are doing if you are using general purpose caps for a switching power supply. Take for example CRT monitors and TVs - a lot of them use general purpose caps in their power supplies. Yet, many of them lasted 10 years or more - even the ones with dodgy cap brands. A lot of my CRTs are actually close to 20 years old now and still function properly. I've pulled caps from a few just for fun, and they tested within specs too. So again, if the designed of the device know what they are doing, they can get away with general purpose caps. But for most things built nowadays, I wouldn't count on it.

Yes, even good CRT monitor use generic capacitors on the secondary of the switching power supply section.

For example a pair of Samxon GS which have very relaxed specifications. They still measures correctly. Replaced them with low E.S.R. counterparts though.

Some CRTs from the 2000s have Elite, they fail in the secondary and develop high E.S.R. on the B+ rail (without failing).

Not a capacitor, but I just came across this knockoff Panasonic battery on Reddit - "Penesamig".
