This RPC lists all the descriptors present in the wallet, not only the ones that were imported, but also the ones generated when a new wallet is created.
It can be verified by creating a new wallet and calling the listdescriptors
RPC, which will contain 8 ranged descriptors that are created for every new wallet.
Also, update the description to get rid of “descriptor-enabled” because this is the only wallet type available now after removal of legacy wallets.
