I've been doing something similar for about 3 years now, neighbors think I'm too lazy to do the "weeding" lol. The way I see it, if I can let the London rocket reseed and drop mulch for me, it's one less chore, plus the bugs get some shade, Meanwhile the roots did my tilling, and when the plant dries up those root passages make the next plants roots go further and further down, all without me having to lift a finger. The most I do is machete the stems low to the ground around this time of year. Fukouka style seeding works well with this method. I am very interested in the work you are doing.
