In highly architected environments, the csShiftJIS and csWindows31J "problem" that is present in ICU would manifest as there being only one API-recognized "preferred name". The present design intent of P1885 in having non-overlapping sets of aliases is in conflict with the desire to associate the "preferred name" as an alias in such situations.
You seem to be saying that the preferred name for both csShiftJIS and
csWindows31J is supposed to be "Shift-JIS" (or so), but an alias is
supposed to be globally unique under P1885.
