I wonder if they aren't trying to make the now obsolete point that if one doesn't wish to contribute and is able to elect a $0 allocation, then the Plan allocations are all impermissible CODA's.
Aside from a deferral election and resultant safe harbor if any, and top heavy if to all employees, any discretionary allocation needs to be the election of the Employer. Doesn't matter if its a partnership, sole-prop, LLC, or fully incorporated entity, it has to read as an entity decision which a resolution helps codify.
