Is that with any other size optimizations? I think by default, most of them (like codegen-units=1, remove panic handling, etc) are tuned for performance, not binary size, so might want to look into if the results are different if you change them.
Stripping can save a huge amount of binary size, there’s lots of formatting code added for println! and family, stacktrace printing, etc. However, you lose those niceties if stripping at that level.
