This is wrong though, check the description of the trait. It is supposed to return the same number as number of enum variants. Substrate can't use
mem::variant_count
because they rely on stable compiler, but we can because we use nightly.There was a problem hiding this comment.

Yeah, this violates the usage of the trait, but the max number of hold limits is hardcoded to
HoldIdentifier::VARIANT_COUNT
in pallet-balances, which doesn't fit into our usage (even in test) so we need this hack.There was a problem hiding this comment.

This is a hack on top of the hack. If it works by accident right now, I'm fine having it temporarily with a TODO explaining why we are hardcoding it to the wrong number. And we should get rid of it before it bites us again.
