This SP release reverts the change and introduces a different approach.
WFLY internals should not be affected in any way.

EDIT: (bstansbe Aug 8) Since this was created, SP2 is out, which fixes a memory leak, so I'm moving the target to that release: https://github.com/weld/core/compare/5.1.1.SP1...5.1.1.SP2
