As of setuptools v67.5.0, a deprecation warning is raised when importing pkg_resources:

DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html

Apparently this has been replaced by importlib.resources and importlib.metadata, which is available since Python 3.7, as well as packaging.

This may be fairly tricky to remove, as src/pyramid/config/assets.py digs pretty deep into the pkg_resources API, namely it registers PackageOverrides with pkg_resources.register_loader_type. However I can't figure out why this call is necessary, I can't find where this loader would be used—Maybe something to do with AssetResolver?

The other issue is that pkg_resources would unzip the whole package into a tmp directory when calling resource_filename, whereas importlib just extracts that single file. pyramid.path.package_path depends on this behavior. Possible solutions:

• Deprecate pyramid.path.package_path, and by extension pramid.path.caller_path, pyramid.asset.asset_spec_from_abspath, and pyramid.resource.resource_path_from_abspath.
• Change contract so pyramid.path.package_path and it's dependents don't work with zip files (or returning zip "path")
• Write an implementation that extracts package to tmp directory, mimicking pkg_resources behaviior.
