:That's not a compelling argument.  Simply noting what a guideline says isn't a compelling argument when people are making arguments for why the guideline shouldn't apply in this case.  To make a compelling argument, you'd have to explain why the other spelling is better on merits, and not just on agreement with a line in MoS.  The "rule" about staying with the original contributor is secondary to the rule that says we should leave well enough alone, absent compelling reasons.  I don't see anybody arguing that the encyclopedia is any worse for the extra 'h', so I can't see the point in adding another pagemove to the history.  I can see a lot of point in agreeing not to move pages around between national varieties of English. -
