Not sure what you mean by 'read-write memory' here. The
null-terminated string isn't going to be stored in ROM or Flash if the
string_view isn't known until runtime.

And as regards memory going unused for 99% of the application's
runtime, I favour this in two scenarios:
(1) When programming a microcontroller, I keep heap allocation to an
absolute bare minimum -- I don't want future allocations to fail
because of a fragmented heap.
(2) Extreme micro-optimisation -- although I very very rarely favour a
micro-optimisation over good coding practise.
