I don't think a shrink is worth it in this kind of business. But perhaps they use the same layout on a finer (less outdated) process (if the actually produce at all and not just sell old stock). Producing the same layout on a finer node is often a first step in conventional chip production when moving from one node to the next before doing the shrink and also leads to better chip parameters as the newer process more precisely recreates the layout dimensions on the actual semiconductor.
