Well, kinda. The value is in meeting the spec, yes, but the "certifiable" part is very often a subset of the actual spec. Sort of like in software how someone will inevitably depend on every feature of a public API (including the defects), a lot of early military electronics depend on implementation details of their component processes, usually by accident. The cost for semiconductor companies is not meeting the spec, it's keeping a production line from the 1960s running exactly the same way for a single customer who buys a handful of parts every year.

The problem with Chinese semiconductors isn't performance or meeting specs, at least not these days. It's counterfeits, life expectancy of the source companies, and the obvious risk of basing your supply chain on a foreign political actor that can leverage this dependency against you.
