...so it's unclear why 2f5f45921b "support
O(U)String::number() for fast string concatenation" added that here.
On the contrary, variables of type OStringNumber can be useful replacements for
calls to std::sprintf (which started to emit deprecation warnings with
macOS 13 SDK now), so this is in preparation for follow-up commits that will
replace many uses of that across the code base with various alternatives.
