I agree with the line of comments - they are a fairly useless archaic feature, especially on packs that have a single vertical row. Parallel rows can come in handy on odd occasions, such as lashing a filthy wet ground cloth to the outside, but there are other ways to skin that cat if no chains are present.
One of my packs intentionally has zero outside pockets (Kelty Slick Rock). Sometimes I find it useful to attach a daypack that is hydration bladder compatible to the daisy chains, but I don't usually carry the full bladder in the day pack when it is attached to the main pack because of weight placement.
You may find the loops a bit more useful if you lace a paracord through them much like a boot lacing - like you see done in elastic cord on many Camel Bak packs. But start the lacing at the bottom and run it up. Load the pack out to full volume first, lace it bottom-to-top, then use the lacing to stow something like a bulky overgarment (parks, perhaps). Trim the ends to that length and carefully fuse ends (keep flame away from pack). Add a cordlock if desired and then knot the two ends together with an overhand knot or a figure 8 knot.
The lacing won't interfere with any other uses of the daisy chains and occasionally comes in useful. Worst case you have an extra length of paracord that you're unlikely to lose or misplace. Figure out how you prefer to stow the excess cord ends to suit yourself.
I believe I would find ALICE or MOLIE attachments more useful if they were thoughtfully placed - simply covering panels with them adds unnecessary weight.
If you want TOTALLY useless, as mentioned previously: Ice Axe Loops. I use ice axes. I've used ice axes for 35 years. I have NEVER used an ice axe loop to stow an axe, even temporarily. [Insert anecdote about clinging to a vertical wall by crampon points and on hammer while screwing in an ice piton with other hand - I have no such stories].
As for attaching climbing gear to daisy chains - I've done that occasionally and every time have been very dissatisfied - YMMV.
I DO carry 4 non-locking 'biners tightly clipped into the loops because they are handy for a variety of uses (bear bags, anyone?) and are readily available on the outside of the pack. Run each thru two loops spaced far enough apart to make them lie flat against the pack and rotate the gates to the inside, open end down. "Toy" 'biners are lighter and cheaper, can serve some of the same uses on the trail, and fit well on daypacks.
My 2 cents.
