I agree this is worthwhile clarifying. To me, between the lines,
this then suggests that paths are entirely unreliable, which I
don't think is what we want. So perhaps some further clarification
could be added to clarify that we're not going to arbitrarily
change paths or their meaning? Or am I mistaken in understanding
that this interface is meant to act ABI-like?
You are right. What about following rewording:
"In case a tag for a path indicates that this path is available in some
case only, this availability might be extended or reduced in future by
modification or removal of the tag."
