Am I right to assume this cache is there to reduce the amount of `Decl`s we need to deserialize from `Preamble`s? Maybe we could fix the cache to also include namespace-level `Decl`s? It should improve performance of the cached completions.

But for a quick workaround we could introduce a separate flag.
