The bug
When multiple mobs/players loads the crossbows at the same time, the sound plays multiple times. This can happen if there are multiple pillagers and piglins loading their crossbows at the same time.

I would argue this issue is invalid, and not a bug. Each individual mob is charging their own crossbow, therefore it is expected that a sound event would play for each entity. Removing sound events for the sole purpose of playing less sounds means that less information is being conveyed to the player about which entity is doing what, which affects gameplay.
Can confirm in 20w49a.
