Yeah, the "downside" of spaced repetition is that you can't stop and expect it to stick (unless you have other means of keeping your memory fresh, such as actually using a language you've been learning). I have some subjects in my stack of cards (10,014 and counting!) that I'm not really so interested in anymore, but I keep them around because I'm paranoid that in a few years I'll want to pick them up again and will have to start from scratch. It's not really so much a downside as an unrealistic expectation, like expecting to keep weight off after you've stopped dieting.
