	return DataFixerUtil.fixUpItemData(
	tag,
	getPlugin().getDataVersion(mcVersion),
	DataFixerUtil.getCurrentVersion()
	);

The data version in HuskSync-DataVersionSupplier may be higher than that in NBTAPI-DataFixerUtil. For example, in version 1.21.8, the data version of HuskSync is 4438, while that of NBTAPI is 4435.

There may be a check in subsequent conversions that directly returns the original data when fromVersion >= toVersion, but I'm not certain.

I'd like to understand and test this a bit deeper what this change means as these version IDs govern how HuskSync calls the DFU to update item stack data versions
