There is no reason why we should not.
unique_ptris less resource heavy thanstd::shared_ptr, and especially the ADIOS2 backend uses some optimizations based specifically onunique_ptr.Users may still provide
shared_ptr-based fallbacks,examples/12_span_write.cpptests this.Note: We still have some scattered untested instances of
std::stringandbooloverloads scattered here and there for dataset-related operations. With #1774, we are now more explicit about which overloads we instantiate. This led to having to remove some of these wrong instances now with this PR, especially from the Python API.
