This is in anticipation of the file containing more generic version functionality soon.
Checks were already in place for RPC version, but this was not sufficient to ensure that the binaries have actually been updated. New checks will now enforce the binary and RPC versions of the directly connected dcrd and dcrwallet, and also the dcrd which is backing the connected dcrwallets.
It was already enforced by version checks in the code but not called out in the docs.

instead of introducing even more TODO, why not write this with context support and pass in TODO from the caller, if that is still needed?

I might just be naive here, but I believe the reality of the situation is that context just isn't needed in these RPC clients.
None of the calls are particularly long running, and in every case I think adding early interruption adds more complexity than its worth. The code is kept cleaner and data integrity is protected if we allow vspd to finish what it is doing before shutting down.
The one thing I might consider is adding a timeout to the context, but the underlying context would still be TODO or Background anyway.
