macOS SDK 10.0 linked to libshiboken2.abi3.5.13.dylib and libpyside2.abi3.5.12.dylib

When installing PySide2 5.12 or 5.13 from pypi, otool -l reports that the SDK linked to 

libpyside2.abi3.5.12.dylib and  libshiboken2.abi3.5.13.dylib is 10.0

otool -l .venv/lib/python3.7/site-packages/shiboken2/libshiboken2.abi3.5.13.dylib

Load command 8
 cmd LC_VERSION_MIN_MACOSX
 cmdsize 16
 version 10.12
 sdk 10.0

...

The reason this is a problem is that macOS 10.15 will require all .app bundles to be notarized.  When submitting my .app bundle for notarization I get the following two errors:

"fred.dmg/fred.app/Contents/MacOS/libpyside2.abi3.5.12.dylib", "message": "The binary uses an SDK older than the 10.9 SDK."

...

"fred.dmg/fred.app/Contents/MacOS/libshiboken2.abi3.5.12.dylib", "message": "The binary uses an SDK older than the 10.9 SDK."

Given that the minimum version PySide2 supports is 10.12, should that be the targeted SDK on the pypi provided pyside2?
