you just lost a whole lot of light absorption, co2 intake and all the perfectly good and useful nutrients stored in those leaves were thrown out. Even if there was a real benefit to removing so many leaves, which zero evidence supports, there is no way it would outweigh all the negative aspects - Two of which are the most important factors -- light and co2. The advice would be not to create huge gaps in your canopy where the most expensive thing you do (light) is completely missing the plant and illuminating the top of the medium and the floor, neither of which produce sugar from photosynthesis for the plants.
Carbon is needed for nearly every molecule that plant will build for cellular reproduction, i.e. 'growth.' Not just stem elongation and new leaves, but also terpen production and flower production. It would be nearly impossible to ovecome that loss for a net benefit, now add in loss of light absorption and you don't even have to test this hypothesis to see it's bro science. Plant biologists would probably laugh at it.
