Nope. If your preference is a penetrating finishes then thats fine.
It will not be as durable or cleanable as a polyeurathane but it is
indeed easier to apply and maintain. This is why poly is usually used
indoors and penetrating oils mostly for outdoor porches.

Woodworking tradition is that the underneath not have finish. Just
too much trouble and too little payoff. I have to say that it is
useful since it further protects the boards and will reduce and
expanding and contracting that occurs with all wood. Having said
that, almost no one would go what is a significant amount of trouble
to finish a surface that no one ever sees or uses.
