bpo fallback option if parameters don't change #3764
Description
eth-clients/hoodi#23
eth-clients/sepolia#119
eth-clients/holesky#136
Osaka fork does not change the amount of blobs, so its been removed from the blob schedule. The idea is that the bpo forks should be different from the regular forks. We should account for this logic.
Action
Write tests for this, and check for bugs in the fallback code path
