It begs the question why British plasterboard is tapered if the "nasty" habit
is European. Basically whether skimming or not (and my research shows this
seems to be a habit confined to UK) the joint is enhance by having a "valley"
created by the two tapered edged butting together. Fill the valley with tape
and jointing compound and you will not get cracking. Butt the non tapered
sides together and all you have to cover the Joint is the skim. Only
exceptional good luck will prevent a crack eventually appearing. Here skimming
is not done. Feather the jointing compound. sand it with a 240+grit paper (I
like 400) and the joint should be smooth enough to run a finger nail over it
without detecting it. Apply a sealer and an undercoat (or a combined product)
and you will never detect where the joint is, even before the topcoats. And I
am an accountant not a professional plasterer.
