I agree, no need for a crossing there. As a newbie to the commuting game, and now a regular on the train that side of the tracks I have no problem crossing. A little patience and the understanding that it is not my right of way is all it takes. Mixed with a degree of common sense.
Yes we all want to get home as quickly as possible, but is 30 seconds too long to wait for a safe time and point to cross. Unless you live opposite the subway or exit, you have no immediate need to cross the roads right THERE.
A crossing will no do any good, all it will do is snarl up the traffic, make the likelyhood of traffic giving way even less likely, and make dumb and ignorant people believe they are safe to cross because the crossing said its safe.
Look up from your phones for a few seconds, remember the green cross code, and try and recall any other place you know with such a narrow road that NEEDS a crossing. Also try and picture how much space a crossing would need. Eliminating most of the parking by Finches and the cab office, making the road almost too narrow for anything other than a Smart car to pass.
