SYSDUMMY1 is "mainly" a throwback. Much of what you used to use SYSDUMMY1 for can be replaced with a VALUES statement. For example, back in the day you used to have to do:
Select :x/:y into :z from sysdummy1
And you're not really using anything from sysdummy1
Now this can be replaced with
Values :x/:y into :z
The VALUES statement doesn't require any FROM clause.

But, yes, everyone should have this object.
