So, this might not be true under a misconfiguration, i.e. someone implements the pallet Config trait for a runtime, but forgets to include the actual pallet in construct_runtime.
Hopefully we do now have lints or warnings to catch this, but on the off-chance that we don't, I'd want to make sure that this expect doesn't trigger and cause a panic in runtime.

This assumption is already used there multiple times.

By removing the default implementation, we can no longer guarantee that the full prefix is "just the hash of pallet_prefix concatenated to the hash of storage_prefix".

Why was it removed in the first place? I see no explanation and commit message is unhelpful "minor improve" 😕

are there any benchmarks for this and the improvements? |
