I don't think people realize that the intent of the rule is to not just keep pucks from being fired over the glass to stop play, but to reduce pucks fired off the glass and out of the zone.

It is now a risk/reward scenario if you are trying to use the glass to clear the puck. In the olden days, if your tried to use the glass and were high, oh well. Now if you want to use the glass, there is a chance of a penalty, meaning you have to aim lower (resulting in either an icing or an interception).

The penalty may be harsh, but it is not like players don't know the risk. Same as the risk of trying to stop a break away by poking at a puck... there is a risk you miss and trip the guy, resulting in a penalty (or penalty shot).

In addition to this rule, I think that you should not be able to ice the puck during a power play (in other words if you ice it, the puck comes back in your end for a face off and you cannot change your lines). And I think if the goalie covers the puck (or holds onto it in his glove), that the defending team should not be able to change their lines either.
