Feature flags are awesome and beyond the obvious AB testing, kill-switch, they allow us to merge code constantly and toggling them on when it is ready (as the author suggests). However, don't forget to do some house-cleaning from time to time. Experiments end (successfully or not), features get permanently rolled-out or killed, and that code will become dept very fast unless you clean your flags and all the code related to them regularly.
