That is only partially correct.

If Android were using idle-time PM and not forced suspend, then yes -- 
not running runnable tasks would be a big problem.

But as it stands, with forced suspend the problem is to avoid delays in
processing wakeup events.  That's what suspend blockers are meant to
solve.  The same problem would occur with idle-time PM if you don't run
all runnable tasks, and it would need a similar solution.
