Hopefully they will make it sooner than later.
Semi-resolved with the release of spyder 6, still waiting for arm64 re-keywording and we have two plugins which are not yet compatible with spyder-6. If the plugin compatibility issue(s) are not resolved in time then I'll just last-rite those plugins (spyder-terminal and spyder-vim).
resolved per https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=1e67fa72af26feb8f436a29b8b63e5691c2896a3
