Any uses for SequenceHold ?

Mma 3.0 has a new Attribute called SequenceHold.
As far as I can tell this Attribute has no useful application.

However there are exactly nine built in functions
that have this Attribute.    They are:
    Rule
    RuleDelayed
    Set
    SetDelayed
    TagSet
    TagSetDelayed
    Timing
    UpSet
    UpSetDelayed

I used a method in Dave Wagner's book to get the above information.
In what way would things fail to work if these function didn't have this 
Attribute?

How did ealier versions get by without SequenceHold?
