scrutinized accordingly. This structure is required for use in snapshot activation
logic.

//! Warning: be very careful when changing this! assumeutxo and UTXO snapshot
//! validation commitments are reliant on the hash constructed by this
//! function.
//!
//! If the construction of this hash is changed, it will invalidate
//! existing UTXO snapshots. This will not result in any kind of consensus
//! failure, but it will force clients that were expecting to make use of
//! assumeutxo to do traditional IBD instead.
//!
//! It is also possible, though very unlikely, that a change in this
//! construction could cause a previously invalid (and potentially malicious)
//! UTXO snapshot to be considered valid.
