Heat guns and pryers are commercially available. I don't think this will change anything there.
Also Stanley's Fubar and CAT 797 trucks are commercially available, doesn't mean I will need one of those to change my phone battery :)
And Pentalobe screwdrivers are also commercially available now, so Apple doesn't even have to include one...
You're wrong about that:
