Yes.

I said "string_capitalize", i.e. "stringobject.c:string_capitalize",
i.e I think 

>>> 'aAaA'.capitalize()

should result in

'AAaA'

We're not doing too well at understanding each other today, are we?

Ah yes.  So in the interests of reducing redunancy, .capitalize should
probably do something usefully different...
