I am thinking who is the person that needs to see this warn. Anyone consuming lightclient data could be affected by an improperly aligned fork, which is a bigger group than the node operator. However, in practice no real network will adopt a bad fork epoch. This should apply to local devnets or experiments.
The intent was mainly for setting up expectation and giving a heads up on the configuration during testing (local devnet / testnets). So yes, this only applies to local devnet and experiments, and we should never see this on a production network. |

Issue Addressed
Addresses this comment: #4946 (comment)
If fork epochs are not multiples of 256, sync committee period may span across forks - this is mostly fine for non-production and testing code unrelated to light client. Adding a check would be useful for identifying issues with future forks / light client testing.
Proposed Changes
Check fork epochs in the
ChainSpec
are aligned with the start of sync committee period, otherwise log a warning durinog startup.
