I feel like glueing on an attachment or putting on gloves (!!) to use your laptop is in fact a much worse solution to the issue of "edge is too sharp" than...making the edge less sharp...

Especially the gloves, come one, that's peak Apple "you're just using it wrong" mentality. Apple made a bad usability decision for the sake of sexier design. It's not your fault, it's theirs. Fix the defect, not yourself.
