People say that interchangeable superzoom ("travel") lenses can't manage good sharpness, yet superzoom compacts do just fine in terms of sharpness. Why is that?

It is possible to make good and sharp superzooms for all formats. They exist. Take for instance the Canon EF 28-300/3,5-5,6 L IS which is a very sharp superzoom for FF cameras. But it's heavy and expensive, around 3000$ I guess. And for APS-C cameras we have many examples. Many say that the Tamron 18-270 is sharp, and probably the best APS superzoom, but when checking reviews it's obvious that it can't match shorter zooms or primes through it's full range. So with an interchangable lens camera there are always better alternatives regarding sharpness. On a compact you have no choice, and the built-in superzoom is sharp enough for compact camera users, who from start made the choice to sacrifice some IQ for a small and versatile alternative.
