In cars with boost *retard* instead of vacuum *advance*, it's extremely important that retard mechanism works. If it gets stuck, you end up with more advance that you want and possible knock.

I regard boost retard devices a design error. Things should be fail-safe. Thus, vacuum advance with stuck mechanism will only give you less advance (=less power) but never go above pre-set total advance. Thus it's fail-safe.
Thank you for your time,
