AssetManifest.loadFromFile missing?

Is it safe to use lime.utils.AssetManifest instead of openfl.utils.AssetManifest, because static method loadFromFile is missing in openfl.utils.AssetManifest.
By the way, why it is missing?

I haven’t used them personally but the quick generic answer is:

Everything that comes from lime works (after all, lime can work on its own without openfl) but don’t expect lime to behave like flash did as it is not his job to mimic the flash api.

Just an oversight
