So an interface is used so that an interface can be displayed
... and those interfaces are ... the same?

You hear how it sounds.

Hands of data! There can be many ways to set data. But after
the data is set nothing should be left _how_ and no special
treatment should later be allowed based on what interface was
used ...

interface |~| data |#| programming logic (code)
           ↑        ↑
           ↑        ↑
           ↑   reinforced
           ↑    concrete
           ↑      wall
         brick
         wall
