I think they also need container to support mimalloc.

pydantic-core/.github/workflows/ci.yml

Lines 260 to 264 in 463ed7a

	- os: ubuntu
	platform: linux
	target: armv7
	container: messense/manylinux_2_24-cross:armv7
	interpreter: 3.7 3.8 3.9 3.10 3.11

They also require the same interpreter because of lacking pypy support ATM.
