Legend
Ok, not a big worry for me, but I see what you are saying. Personally I wish all publishers would relay less on the statblock and put more flavor information in the lore so it leaves space of interesting mechanical bits to be in the statblock.Sorry, I thought i had laid it out, let me try again.
-They replace things like keen senses with a bonus to perception in the statblock.
-Dms may not be aware why the perception is higher.
-DMs that would have noticed keen senses don't play the creature as if it had a special ability.
-If the wording in the lore retains a keen senses description, all is well.
-If the wording in the lore doesn't mention any such trait, then it is lost and no longer a part of that creature.
Therefore I hope all these mechanical simplications don't make traits inherent to the creature "disappear"
Now regarding the simplification we are seeing in the 2025 MM statblocks: In general I am in favor and in general I would like that flavor to move to the text as you suggest. I think that may happen in some cases, will it happen for keen senses? IDK, but my guess would be no.
However, we can look at an example from the previews they have shown.
The 2014 Kuo-toa reaction as flavorful descriptive text in the statblock:
This has been removed from the 2024 statblock:
However, the text outside the statblock of the 2024 Kuo-Toa adds some of the back. Notice the last sentence.
So maybe they will do something like you're suggesting. I still don't expect it for keen senses, it seems to obvious to me, but who knows!
