Well, a change at this caliber begets other changes as well. Riot could easily change the numbers for flat penetration to compensate for this issue.

An interesting thought I believe would make flat penetration viable in another degree is to allow flat penetration to dig below 0--normally when flat penetration exceeds the amount of resistance the enemy has, it defaults to 0% damage resistance rather than increasing the damage output. This increase in damage output could allow for an different use for flat penetration runes as minions and jungle monsters don't have very high resistances.
