Well, I supose this will get me flamed and added to many ignore lists.....
It seems to me that when someone speaks about a technique, there is an implied context. In a multiple attack training situation (ie 3 ukes, one tori with sensei and class watching), I suspect that dropping down to one's knees to perform swari waza techniques is probably not the best choice for tori. Tori is probably best served by remaining standing.
Does that mean swari waza techniques are pointless? I don't know. I'd agree if someone said they were (given a specific context) and I'd agree if someone said they were not (because of benefits in other areas). I don't think labeling a technique as "pointless" is any threat or belittlement of a martial art or martial system given a specific context per se.
Ducking for cover,
