It's possible to trick the spam-crouch slowdown by additionally spamming the A+D/moveleft+moveright keys. It refreshes the action and animation for the crouch after you move or something like that. I like to spam crouch while bunnyhopping as well because it kind of breaks your hitbox and wiggles your playermodel all over the place.
