This does only trigger in specific conditions, but even so, without ethereum/execution-apis#285 being fully supported across the ecosystem, this might be a bit aggressive to quit on mismatch.

I came up with a slightly different plan during the weekend. We can quit here, but we'll allow the user to silence the check with a command-line option. The goal is to inform the users that they must do something for the upgrade while allowing them to continue operating their node while they are setting up a full Ethereum node with an Engine API.

https://bordel.wtf/ currently states
Total Terminal Difficulty of 58750000000000000000000 is expected around Thu Sep 15 02:29 2022 UTC, i.e. between Thu Sep 15 01:00 2022 UTC and Thu Sep 15 03:59 2022 UTC
But probably better here to go with the earlier of the plausible estimates (so the wenmerge one is probably better)
