If we were to have blind spellbook medding, and you feared getting aggroed or trained or other danger, would you med out in the open? Near a camp of mobs? Near a train highway? Nay, you would med somewhere safe. You would invis before medding. You would tell your groupmates you were medding and please guard you while you were in deep concentration. And that was part of the classic experience.

Not only is spellbook medding part of classic, it's easy to overcome.
Speaking of which, people who remember from back in the day, did people say "medding" to announce that they could no longer see beyond their spellbooks?
