That's a contradiction of terms, Runflats and great handling in the same sentence.
On paved roads, wet or dry, RFTs are non-responsive and lack any feel thru the wheel.
RFTs can "save the day", but they can also "drain the wallet" (replacement is required after driving them without air for any significant distance).
Question; What can a repaired RFT can be trusted for?
Answer: Rolling a vehicle out of the garage.

Not sure what brand or type of tires you have personally experienced but my Dunlop have soft tread and a patented stiff sidewall that gives very good handling performance. My x5 handles better with the new tires than with the previous set that were similar in nature but not run flat. I use winter tires year round so I have better grip wet or dry than any similar tire that is all season not even close.
I drive in Chicago a lot and have countless times slipped and slided when it just started raining because of the oil film on the road. When I bought my x5 it came with winter tires and I immediately noticed I no longer slipped around on the oil funk in Chicago. I've never gone back to the slip and slide of summer tires and never will.
The stiffer sidewall offer about 500 pound more capacity per tire. That is extremely helpful when I have 1100# of tools in the back.
Not sure where repaired rof comes into play. The tires are not substantially more expensive than quality tires in the same performance class and any tire will be trashed if goes flat at speed and would need to be replaced. The one time I had a flat with ROF I was going under 30 and heard a weird sound when the valve stem exploded.
I drove about four blocks until I find a place to pull over. I was able to repair the valve stem with silicone tape and get the tire to take air and drive with no pressure loss until I got to a shop to replace the valve.
The point is: with ROF you are much less likely to need to replace the tire because of a short lived no air situation. In most my flat tire situations in my lifetime, ROF would have meant no changing the tire just filling with air as they were parking lot no air situations.
My one flat ROF experience where I was 6 hours from home and simply drove to Sam's club where they replaced the valve for free saved me more than the cost of the tire in one event. (no tow, no emergency tire rack order, no local garage to mount a tire, no extra hotel day).
I bought another set for my wife's x5 it didn't seem right I would have ROF if she didn't.
I bought a couple used spares for about $100 each to have on hand for instant replacement of a failed tire. The primary benefits of the ROF tire are maintaining nearly full control with zero psi and not needing to swap a spare in inconvenient places or times.
Maybe because I run winter year round I don't lose any handling performance I also drive in grass and through the woods more than occasionally and the grip is tenacious.
The winter tires definitely add a little more hum to the driving experience but it is music to my ears.
I have no idea what you are saying about road feel since I can instantly tell when I'm on a different type of surface where I have less grip when I steer. I would also estimate that the stiffer side walls effectively drop the apparent ratio by 10 and give me very responsive control.
