With the new item component system, a functionality has been removed/replaced. We can't have an advancement that would trigger if the player is wearing an equipment with a specific enchantment, as now the comparison is of type "is exactly" instead of "contains".

Steps to repro:

• have a datapack adding an advancement such as the one attached
• go in the nether with a chestplate enchanted with the binding curse and any other enchant

Expected behavior (as before):

The advancement is triggered.

Observed behavior:

The advancement is not triggered. It can be triggered only if the chestplate has only the binding curse enchantment.

Although I understand this behavior could be useful, I believe the previous one is more interesting. At least being able to choose the way the predicate is being tested would be nice.
