The most difficult part is handling parent-child relations correctly: when a parent is applied, the children should be moved accordingly, and when applying a child, it should not include transformation from unapplied parents. All this requires walking bones as a tree, instead of a flat list. Limitation: Applying bones with non-uniform scaling without also applying children will distort non-rest posing on said children for reasons related to T54159 (basically, non-uniform scale plus rotation creates shear, and Blender matrix decomposition utilities don't have tools to deal with it).
