Reading Friedman's "British Frigates & Destroyers" there seems to have been no problem in grinding out dozens of studies and designs few of which were ever built. A design time is per head relatively expensive but in total hardly makes the rounding error when you start building. I suspect people move on because so little is actually built
Had you understood the context of that book, you'd also realise it was a different construct and a vastly different periodicity.
The single worst thing you can do is lose your design capability. It is incredibly difficult to reconstitute it, as most western navies, shipbuilders (including the US) are finding out.
