+Alternatives
+============
+
+A possible modification to this proposal is to entirely remove the Sprout-related fields
+``nJoinSplit``, ``vJoinSplit``, ``joinSplitPubKey``, and ``joinSplitSig`` from the V5
+transaction format. While this would effectively prohibit migration transactions that
+directly move funds from the Sprout pool to the Orchard pool, Sprout -> Transparent and
+Sprout -> Sapling transactions would still be supported when using the V4 transaction
+format. This proposal is appealing from the perspective that it would reduce the
+complexity of the NU5 upgrade in the following ways::
+
+* V5 parsing and serialization code would not need to take these fields into account.
+* ZIP 244 [#zip_0244]_ transaction identifier, signature hash, and authorizing
+  data commitment computations could be simplified to exclude consideration of 
+  these fields.
+
+This change would mean that in the future, removing the support for the V4 transaction
+format would also effectively end support for Sprout transactions on the zcash network,
+though it might be possible to restore limited support for migration via a future ZIP 222
+[#zip_0222] extension or by other means not yet determined.
