Unfortunately this results in code duplication, which makes going back and editing things annoying (twice the work, and you better not forget one of the checks). I usually only add in the extra clientside check if it's something that's going to be triggering extremely frequently. Of course this is a matter of preference but this is what I've found to be a nice balance.

The code duplication issue is sadly a hard problem to solve, even outside of Graal, and I haven't really seen a solution I've liked anywhere to port it, so I guess we'll just have deal with it for now in the critical areas.
