 From my point of view this is not the same.

Jack wants "anybody but my boss"

worker_5 is "the 5 guys who are my coworkers today"

in the .com era you would have had to grow this group daily and the names
all change. In the .bom area you have to shrink it daily and the names
all change. Either way, the set of people "anybody but my boss" is not the
same as the set of "these guys who may change names or cardinality on a
daily basis"

worker_5 is a ton more work to keep set up correctly.

I used ACLs on Data General AOS and AOS/VS in 1981, and I have to say I
really got to like them. It's a very old idea but that doesn't mean a bad
idea.
