Hu?  It does not break it any more then the current state.  The systemd
package already ships an EFI binary without any integration.

systemd-boot can add proper SBAT as far as I see.  Maybe not in the
version currently on Debian unstable.  Also I see some calls into
SHIM_LOCK.  So there is both SBAT support and support for the shim
verification protocol.
