(I guess you also assumed the current cache is smaller than the old
max-cache-size).

I've not tested the behavior, but in my understanding of the code,
nothing will happen by just changing the max-cache-size.  Cache
cleaning will be triggered first time a new entry is added since then.
It should be the same for both 9.4 and 9.5 (while how the cache is
cleaned is totally different).
