The arm docu says that
"X30 is typically used as the link register (LR)"
and X29 might (depending on compile options) also have some special  meaning.  Maybe that's why they are omitted on Windows/BSD/macOS . On the other hand it seems not to hurt to output them too.
Maybe some arm/aarch64 experts want to comment?
