There are a few checks across the server code base that acquire a snapshot of the server's FCV and check if the FCV is initialized using FCVSnapshot::isVersionInitialized, for example: 1, 2, 3, 4.

We should review those checks and determine if they should take Operation FCV into account.

Note that most usages of FCVSnapshot::isVersionInitialized are part of an antipattern for checking feature flags (SERVER-84149) - this issue is about the checks that are not part of that antipattern.
