You can always imagine that in the HPMoR fictional universe, Fate/Stay Night came out in some form much earlier—same way that variations of ‘Gargoyles’ and “Death Note” seem to have been wizardly entertainment earlier than their real counterparts came out in the real world....
Anyway, it’s not really useful to fuss about the chronology of fictional references too much, either from the point of view of the readers, nor from the point of view of the author...
Personally, I find shout-outs less jarring than straight out references to Harry having consumed fiction that shouldn’t exist yet. The Tragedy of Light isn’t Death Note, it’s The Tragedy of Light, even if the real life inspiration is obviously Death Note.
