The set of data committed to is a superset of data which can impact the TXID of the transaction,
other than the inputs. This ensures that for a given known input, the TXIDs can also be known ahead
of time. Otherwise, CHECKTEMPLATEVERIFY would not be usable for Channel Factory type constructions
as the redemption TXID could be malleated and pre-signed transactions invalidated.

I assume that it is trying to refer to »transaction malleability« but it's the first time I've ever seen »malleated« and it just feels like change conveys the same meaning but is clearer.

Same here - I would keep the word "malleated" here.
