If it isn't causing condensation, do not remove any more leaves. Simple :P A bunch of overlappying leaves or leaves resting on the walls are things to avoid. Sometimes you can bend or shape the plant to avoid it or support it away from walls, etc. The last resort is to prune leaves.
Leaves do many things beyond absorb light. Even if shielded, they are value-added.
Storage, manufacturing building blocks, lungs, light absorption... leaves are important. The intake of CO2 is your limiting factor. Reduce leaves = reduction in growth potential - and that includes building flowers... all growth. Don't need intensie light to engage in transpiration.
have a good reason to prune off a leaf. If you haven't overcrowded the canopy there should be very limited need to remove leaves at any point. Based on local environment,that plant 'wants' a certain number of leaves. if you deprive it of that need, it'll try to grow more -- this is why defoliation sometimes delays flower. if a plant has too many leaves relative to local environment provided, it will shed them. There is some sort of feedback mechanism in regard to this even if a plant doesn't have a CNS. Bottom line, the plant knows a hell of a lot better than us if it has too many leaves.
