Well, obviously such increase in the visibility of dependencies is not a
comforting or welcome thing, but let's not forget, that those dependencies
truly are there :-)
I'd ask the opposite question: given the extent and nature of the relations
exposed by this change, do we want to keep wholesale hiding them with the
current implementation?
Or in other words, are those particular dependencies (stemming from
'extend_recipe_sysroot') so irrelevant for the overall signature and sstate
management, that it is justifiable to keep ignoring them in such a unique
way and on such a fundamental level?

Unless it is truly a desirable situation and the whole subject can be
dismissed, what would be the recommended way to tackle it?
