The precise tag is a defining characteristic of a classic "roguish" weapon, technically it means you can use DEX when Hack and Slash with it.
Default weapons list is very short in Dungeon World, and only two weapons from it has the "precise" tag. By contrast with D&D, a DW dagger is not precise. This oddity was noticed on the PbtA forums:
It appears to me that the intent is to make "precise" a rare tag, via cost. It costs 25 coin for a rapier (the cheapest precise weapon), and 8 coins for a short sword/axe/mace/etc. The only difference is the precise tag.
I wonder was in intentional, or is it just an oversight. There was no official answer tho. Since designers' reasons questions are off-topic here, I'd ask it another way. In terms of game balance, does adding 'precise' tag to daggers break anything? (by "balance" I mean that game should feel fair, and nobody steals the spotlight from any PC) Should the DM tweak other tags, consequences or price accordingly? How exactly?
Bonus points for those who tried this in their games.
Double bonus points if you actually know what the developer's intent was.

The game self corrects for overpowered characters because XP gains are largely driven through failed rolls.
The whole point of using DEX for STR is I assume the sheet the player is running is optimized around DEX (or thats their player preference for the character). In a large DW game (I was a player) the GM explicitly had another player run their Character with 18 in all of their attributes to see the effect this had on gameplay. While that character certainly succeeded at basic moves and their starting moves more frequently then the rest of the characters did, they also found it really difficult to level up as most of the XP the rest of the party received for failed rolls was inaccessible to them.
The game is largely driven through tags; if players want to add a tag to an item that doesn't exist make them pay for/earn it in some way.
You can of course just add the tag as you see fit as GM, but generally tags are driven by the narrative so if a character wanted to find a particularly well-balanced dagger for street fighting per se they should seek one out in the world beyond the standard fare at weapon shops - or they should commission one from a blacksmith.
