Why don't we just use an fletching_table?

Why don't we just use an fletching_table? It's really simple.

Since crossbows can't use bow enchantments, we could use the table to craft special arrows that are different from potion arrows. For example, arrows made with blaze rods could ignite, ones made with whirlwind rods could have knockback or explosion effects, and arrows made with bones wouldn't have an attack delay.

Honestly, crossbows' multishot even bounces two arrows back after hitting a mob, so I really need these arrows with no attack delay.
