Having it is pointless if your SNR is so low that it costs more money than simply waiting for the bug the next time it comes up.

IMO, if a bug never surfaces again, that's not a bug I care about anyway. Keeping all generated data in case someone wants to see the record from a bug 3 months ago is absolutely pointless - if it hasn't surfaced again in the last three weeks, you absolutely have more high-priority things to look at!

I want to see this mythical company, where a paid employee is dedicated by the company to look at a log from 3 months ago, to solve a bug that hasn't resurfaced in that three month period!
