I am wondering whether we want this happening on the rest of the wheels too.
Should we just try to add this section to the pyproject.toml:

[tool.scikit-build]
install.strip = false

We manually strip debug symbols on wheels when building but I am unsure we want to strip all as discussed in the past. Details here:

@rok what do you think?

For my understanding - what level of symbols do we want to distribute in wheels? Debug or less? Should we have debug wheels (that we perhaps only distribute through github and not pypi to save pypi quota).
How about distributing debug symbols separately? (see generated prototype here https://github.com/rok/arrow/pull/59/changes)

I think we can merge this. This seems to have been the behaviour since scikit-build-core 0.5 and we've had several releases with it. No need to change current behavior globally.
