Given how long our current behavior has stood, I think it'd have to be
a pretty convincing argument. As you say, there'd be some serious
compatibility costs to changing that behavior.
IIUC, SJIS<->Unicode conversions have always been a squishy thing
because of inconsistencies between the various versions of "SJIS".
I'm not seeing a good reason we should regard Windows' behavior as
authoritative here.
I'm not saying I can't be convinced, but "Microsoft does it that
way" isn't enough to convince me.
