This should prevent the failed transactions that are encountered when issuing two or more in a short space of time. Using a feature trigger (hard fork) to release this, to avoid potential consensus confusion around the time of the update (older versions could consider the main chain invalid until updating).
Note: this relies on (a modified version of) liblitewallet-jni which is not included, but will ultimately be compiled for each supported architecture and hosted on QDN.
LiteWalletJni code is based on https://github.com/PirateNetwork/cordova-plugin-litewallet - thanks to @CryptoForge for the help in getting this up and running.
Note: it's important that this timestamp is set on a 1-hour boundary (such as 16:00:00) to ensure a clean switchover.

Lite nodes can't sync or mint blocks, and they also have a very limited ability to verify unconfirmed transactions due to a lack of contextual information (i.e. the blockchain). For now, most validation is skipped and they simply act as relays to help get transactions around the network. Full and topOnly nodes will disregard any invalid transactions upon receipt as usual, and since the lite nodes aren't signing any blocks, there is little risk to the reduced validation, other than the experience of the lite node itself. This can be tightened up considerably as the lite nodes become more powerful, but the current approach works as a PoC.
This is currently for name registration transactions only, but can be adapted (or duplicated) for other transaction types when needed.
Note: this switches from a greater-than (>) to a greater-than-or-equal (>=) timestamp comparison, as it makes more sense this way. It shouldn't affect the previous transition since there were no REGISTER_NAME transactions at that exact timestamp.
The command used was:
./protoc --plugin=protoc-gen-grpc-java=/Users/user/Downloads/protoc-gen-grpc-java-1.45.1-osx-x86_64.exe -I=src/main/resources/proto/zcash/ --java_out=src/main/java/ --grpc-java_out=src/main/java/ src/main/resources/proto/zcash/service.proto
Then repeat, replacing service.proto with compact_formats.proto and darkside.proto
Darkside isn't needed for mainnet functionality, but included for completeness, and might be useful for testing.
