q: since this is now part of dest chain config args - do we still need it in allowListConfigArgs? There are now 2 ways to change the allowlist - is this intended?

This just enables it when a new chain it set, to prevent unauthorised access to a private chain. The other method is still required to set the actual permitted addresses

For the first option it makes sense, for the second option - we can always batch 2 MCMS calls:

  1. setDestChainConfigArgs
  2. setAllowlistConfigArgs

Seems slightly redundant to have the flag twice
