So angstroms fits with that.
I see no reason to force people to use any particular unit, if they really wanted to measure everything in some ridiculous unit like yards (I apologize on behalf of the English for saddling the US with the Imperial system). But it makes sense for it to be explicit that by default we deal in angstroms, rather than implicit as it is now.
