I use the grip handles for painters on my composite canoes that don't have factory drilled holes.
In my opinion, Tugeyes are GAS things for most canoeists. But so are Ace playing cards in the spokes of a Schwinn.
The OP specifically asked about Tugeyes on composite canoes. . . . I've never needed to attach rope a couple of inches above the water line and don't foresee a need ever to do so. . . . .

My opinion is that Tugeyes placed in the recommended lining position, a couple of inches above the waterline, are something that would be a GAS thing for me because I have never needed lines attached that low on a canoe for any reason.
Here is where Hemlock advises putting Tugeyes for lining a canoe a la Bill Mason. I don't do Bill Mason, so these holes are much too low to be practical for anything in my canoeing world -- other than when I'm stricken by Gear Acquisition Syndrome, usually in February.
Yes, but Tugeye's can be used for various types of attachment points not just for lining rope attachment. I thought this topic was about placing Tugeyes "as low as possible" "for lining", as Dave mentions in his OP.
Since the cutwater point will vary with both keel (rocker) line shape and gear load, the correct attachment point is somewhat ambiguous. In any event, it's clearly much lower than one would put the usual and convenient grab loop holes.
