Allowing arbitrary hex data to be wrapped in
sh(),wsh(), or even within theTREEargument of a
tr(KEY, TREE)descriptor enables the representation of currentlyinexpressible information.
Specifically, the absence of this feature limits the representation of non-standard redeem
and witness scripts. This occurs because they can currently only be represented as top-level
raw(HEX)descriptors, which retain only the output script information and lack the abilityto preserve the actual script.
This work stemmed from discussions with @sipa and @achow101 about the legacy
wallet migration path, particularly while investigating migrated descriptors that lacked
information about the script they were supposedly migrated from.
Additionally, issue #24114, specifically bitcoin/bitcoin#24114 (comment), provides
historical context and highlights other valid use cases enabled by this behavior change.
