This issue occurs since 24w13a. 

Although the Wind Charging, Weaving, Oozing, Infestation, Raid Omen and Trial Omen effects cannot be obtained from /effect without experimental features enabled, you can use item components to get these potions, splash potions, lingering potions and tipped arrows. 

Wind burst, Density and Breach cannot be obtained by /enchant, but their enchanted book or items can be obtained as well. 

It seems that the power of item components breaks the limits of experimental features. Powerful item components! 

How to reproduce:

1.Create a world without any experimental feature. Remember to allow commands. 

2.Enter these commands:

To obtain the Potion of Wind Charging (in either of two ways): 

/give @s potion[potion_contents={potion:"minecraft:wind_charged"}] 1

/give @s potion[potion_contents={custom_effects:[{id:"minecraft:wind_charged"}]}] 1

The Enchanted Book with wind burst III: 

/give @s enchanted_book[stored_enchantments={levels:{"wind_burst":3}}] 1

The Diamond Sword with wind burst III: 

/give @s diamond_sword[enchantments={levels:{"wind_burst":3}}] 1

It's worth it to fix it before 1.20.5 release. If Mojang plans to fix it after 1.20.5 or not to fix, please resolve it as Won't Fix. I guess fixing it in 1.20.6 or later is meaningless.
