but you can make a OUString point to another 'immutable content'.
iow it is not OUString that is immutable... but it's 'payload'.

I may be wrong, but I assume that the reason OUString is like that is
not just to save a nCapacity... but also because there are assumption
you can make if that property is true (that OUString only point to
immutable data, regarding memory allocation, copy, clone etc...
