[FR] - Misleading `unsafeHashableScriptData`

Area Other HashableScriptData

Describe the feature you'd like We have been successfully using unsafeHashableScriptData however its description recommends NOT to use it:

Warning: Creating HashableScriptData from a ScriptData value pretty much guarantees the original bytes used to create the value will be different if we serialize again. Do not use this.

However it is unclear how to construct a ScriptRedeemer from ScriptData if we shouldn't use unsafeHashableScriptData - in general, if usage of unsafeHashableScriptData is discouraged, it is unclear how to go from ScriptData to HashableScriptData.

Please either change the description of unsafeHashableScriptData or provide other (safe?) means going from ScriptData to HashableScriptData.

You can use fromAlonzoData in this way:

import qualified Cardano.Ledger.Plutus.Data as LPD
import qualified PlutusLedgerApi.V1                as PV1
import qualified Cardano.Api.Shelley               as C

toHashableScriptData = C.fromAlonzoData . LPD.Data @ledgerEra . PV1.toData

[Swordlash]

But I don't think it matters if you're creating the data from scratch (programatically) rather than by deserialisation from a bytestring.
