   I have a private key disabled descriptors wallet which I use to watch transactions. Upon fetchings the UTXOs using listunspent, the spendable is true. Documentations says: "spendable" : true|false, (boolean) Whether we have the private keys to spend this output. Shouldn’t the spendable be false for this case, as it belongs to wallet where there is no private keys? here is wallet info:

   The docs need to be updated, spendable is always true for UTXOs belonging to a descriptor wallet, including ones without private keys.

   Considering that the legacy wallet can no longer be loaded, will this field always be true?

   Then the field is deprecated as commented by @w0xlt here. Thanks @achow101
