The KLocale default page size was actually used in very very few places, and usually by mistake when they really wanted the default printer paper size to render a print-out to, leading to lots of issues with printers complaining about the wrong paper size. Allowing it to be set in KLocale led to a lot of user confusion on the difference between the two, there are some long and rather ugly bugzilla threads on the matter I do not wish to revisit. I'd also argue that the default page size needed for one app is not necessarily the same as for some other apps, depending on their use case. Writing a letter I probably do want A4, doing a flow-chart I usually want A3, doing a presentation I want projector screen 4:3 ratio, doing a painting in Krita it's whatever size the artwork needs. I'd rather not reintroduce all that, instead most use cases should check the default printer page size to render to, or if they do need a page size then if QLocale::measurementSystem() == QLocale::ImperialUSSystem use Letter, otherwise use A4 (this is exactly what the KLocale files are set up as, only the USA isn't A4, and PDF printing in Qt does this to choose its default page size too). In Calligra I could see the case for having the ability to set a default page size for your apps to follow as you are in the business of generating new documents with fixed page sizes, but very few other apps actually need to do so (I'm struggling to think of more than lyx), must just want it to print to. I think this belongs in Calligra settings. Cheers!
