The Paper method was chosen for deprecation because it was more restrictive in that it has an isGliding check.

Subject: [PATCH] Avoid error bubbling up when item stack is empty in fishing
|
|
loot
|
|
|
|
This can realistically only happen if there's custom loot active on fishing
|
|
which can return 0 items. This would disconnect the player who's fishing.
