A unique drop for Silverfish (Silverfish Scales!)

With the release of 1.21: Tricky Trails Update, a number of brand new potions have been added to the game, with those being: 

-Potion of Weaving,
-Potion of Oozing,
-Potion of Wind Charging,
-Potion of Infestation.

All of these potions are either crafted with unique items directly dropped by a specific mob tied to it (Breeze Rod), or alternatively a block which is derivative of & explicitly, directly tied to a specific mob in an intuitive way (Slime Block, Cobweb), that is all except for one of them; Potion of Infestation.
Potion of Infestation is the odd one out among the new potions from the 1.21: Tricky Trails Update.

Thus I propose for the Silverfish to finally get it's own unique drop; Silverfish Scales!

Those would be much more intuitive & natural of a potion ingredient for the Potion of Infestation.

Moreover, they would also make aquiring the Potion of Infestation more difficult; 1 stone block being able to create 3 potions which can all spawn substantial amounts of Silverfish seems OP & unbalanced, especially when we compare them to other potions added in 1.21: Tricky Trails Update. To create all the other potions you must have first come across a Breeze, Slime, or an Abandoned Mineshaft/Trail Chamber, meanwhile Potions of Infestation are so much easier to create & don't require you to have come across a Silverfish before.

Adding Silverfish Scales would adress another inconsistency; Silverfish are one of the few hostile mobs which drop nothing besides XP after their death.
