They actually just today released an update [1] with fixes for sleep:
"We now have a cpuidle driver, which significantly lowers idle power consumption by enabling deep CPU sleep. You should also get better battery runtime both idle and during sleep, especially on M1 Pro/Max machines.
Thanks to the cpuidle driver, s2idle now works properly, which should fix timekeeping issues causing journald to crash."
