 I see. Using boost::string_ref in that way (local variable) would raise a
big red flag for us. So i understand that the change does add some safety,
but it also breaks usages that are completely fine. We 'solved' the safety
issue with a really simple rule (only use boost::string_ref as function
parameters).

That's exactly what I said in my blog post. Function parameters are a
special use case that require a different type, that type is
std::string_view, for everything else a boost::string_ref that doesn't bind
to rvalues could be repurposed.
