Have you any reference from a manufacturer that is a design criterion?

Don't say it isn't so, but I've never heard or seen it mentioned in any
literature which one would think would be so if were an actual design
feature.

I just did a search of the entire product brochure for the Square D QO
breaker series and there's no mention of "age" or "aging" or
"sensitivity" throughout.
