My laptop is set up with secure boot but without shim using a shim protocol thin layer to check the kernel signature against db variables: https://git.kernel.org/pub/scm/linux/kernel/git/jejb/efitools.git/tree/ShimReplace.c and I haven't seen any breakage, so not having a shim that does measurements works for me all the way up to -rc4.
