My very limited experience with Peak is you can slack line it but it tends to also like foil positioning. One benefit is if it collapses it opens quick and of course light weight. You will miss hot air effect and from what others are saying is single skins tend not to slack line. Which makes sense because they sit deep. I am cautious of them as I like slack line and it seems so many are confused what that means and what true slack line is possible. True slackline is basically no kite is felt in pull and no kite input is really possible with the bar ... amazingly because... the lines are slack.
If ribs (cell walls) are to be having vents simple overlapping flap type vent is usable, but pressure will be lower than with a normal air intake at stagnation point.
There is no reason that they cant have restriction to the high pressure point. The intention of attaching to just the wall is one give an anchor for the sock so it doesn't sit at the LE allowing water in and two reduce weight by allowing a thinner sock.

Really? You tested this? Or are you as seemingly usual just talking out of your ass. The Peak4 seems to have significantly improved water relaunch, I would think the tips have something to do with it.

Happens on ... existing foils
partly rigid wingtips may cause only problems (bowties).
Existing foils bowtie, yep there is potential, but what is that? How can you assume it is not worth it? How much testing have you done? Waves? Slack lines? Collapsing 100's or 1000's of times? Videoed results? Double blind? Or... the usual?
I think I know what is logical development to closed LE single skin kite but I don't know if I have enough motivation to make it reality.
Yep the usual, you could do it but wait for it you haven't. Same criticisms you level against most kites. I think you design tube kites and wouldn't have a hope in hell of designing a competitive foil kite.
