Review comment:
Nit: all of the stuff that gets added due to expiration should ideally
be inside of the `if (hasExpiration)` block or in the return statement after
that section if it's for non-expiring cache (i.e. the
`identLoggingRemovalListener` here).
Can you split this line into that block (and the block after it for the
`identLoggingRemovalListener`.
This would also remove the need for the local variable `hasExpiration`.
