Same sound, different diacritic position

[nardog]

There exist pairs of segments that represent the exact same sounds but differ in the placement of diacritics: [j̊]/[j̥], [ŋ̊]/[ŋ̥], [d̥ʒ̊]/[d̥ʒ̥], etc. Shouldn't these be merged?

I also see transcriptions with stacked diacritics like [l̪̥], but if you allow superscript versions of canonically subscript diacritics at all, why not transcribe them like [l̪̊]?

And why is the devoiced diacritic the only one you use two different versions of? For example, it seems to me [ɹ̪̩] is better transcribed [ɹ̪̍] (again, if you allow superscript versions at all).

this will need to be fixed in the dev repository in order to fix it here. @xrotwang feel free to close in favor of phoible/dev#225 (unless you prefer to leave it open until this change actually makes it into clld/phoible)
