It came on my radar a few months ago when I first started noticing this rot problem. Then recently I saw that it was getting quite hyped and people have been singing its praise for solving this exact problem. So I'm giving it a shot.
Can't say for certain whether it will work out well or not yet, but based on the feedback I've been seeing from others, I'm hopeful.
