Agreed, although this is probably an enhancement rather than a bug.
Have you tried using eu-strip (from the elfutils project) or llvm-strip ?
They may produce the results that you expect.

Because they are needed and used. At least by ld.so on Linux boxes.
The notes contain information about the architecture extensions needed
by the application that is being loaded and the loader makes sure that
these are available before starting to run the code.

It would probably be worth your while enhancing your loader so that it
can cope with these segments. Even if it just ignores them. It will
make things simpler in the long run.
