KTM porous engine casting

When my bike got a porous clutch cover oil leak (like a couple other guys on here) after going at least 5,700 miles completely dry. I started doing a little research, apparently the rc8 motor suffers a lot from this. So the rc8,1190 adventure and super dukes that all share that engine case, are suspect. Even though my clutch cover was replaced and as of yet isn't showing any signs of leaking. I can't feel content that the issue is a thing of the past. Will this case be good from here on out? Or will it go 5,700 miles before the next leak or less or maybe even more?
Gaskets I can work around as far as stopping a leak, usually with Honda bond ht or three bond 1211. Yet I have no idea how to stop a porous casting from leaking. I have 10 months left under warranty, if everything is corrected by then and everything goes smoothly from there on out, I'll be happy considering I went against my own rule to never buy the first model year of a car or motorcycle.

The porous engine casing is a by product of the pursuit to make anything lighter. After ABC mentioned it I looked in to it and the trend is to make non structural parts as thin and light as possible and deliberate mix air in to the aluminium cast to make it lighter.
If you're unlucky it creates a channel or pinhole and there is your leak.

I sucessfully stopped mine from leaking by cleaning the pinhole and center pointing arround it to tap it shut using a gentle touch and a tig tungsten.
I then applied JB weld and problem solved till it got replaced under warranty.
When I say gentle touch I mean gentle as it is easy to punch a bigger hole when ham fisted.
On my bike it was the bigger clutch cover and no big deal to replace, don't know what they do when it is the engine casing itself.
Myself I would be highly reluctant having a KTM mechanic pulling the whole engine to bits to replace a half engine casing.
