Fragment of a discussion from User talk:Rua
FWIW, what CodeCat describes here is what we do for certain Japanese entries, such as せんし (senshi, with multiple pronunciations) or せいたん (seitan, with just one pronunciation for all terms with this reading). I know there are examples too where we have a top-level Pronunciation that applies to multiple terms with distinct and explicit Etymology sections (as opposed to implicit etymologies for the two examples here), but I cannot think of any at the moment.
