doubt it, i mean what would be the point? armour already has some items with disadvantage to stealth and others without + amount of armour checking Dex just adds another pointless thing the game has to keep doing
just take medium armour feat to put on gith armour or add 2 dex and wear drow armour
It allows a medium armor user to get 1 extra AC (if they have enough DEX) and also avoid the penalties for stealth while wearing Half-Plate (15 AC). There are medium armor without penalties to Stealth - i.e. Breast Plate (14 AC), but that comes at the cost of having 1 less AC than Half-Plate.
So basically the benefits compared to someone without the feat are (via using half-plate):
- If originally using Half-Plate: (+1 AC, no stealth penalty)
- If originally using Breastplate: (+2 AC)
