I'd imagine as soon as the patent expires you'll see much more open 
discussion about SEH. Until then no one is going to feed the lawyers. 
Do remember clang is pretty much exclusively developed by large 
corporate entities, and those engineers know not to worry Legal or 
it's a whole load of hassle. I speak from experience at BlackBerry 
where I once worried Legal and very much regretted it for the many 
months of never ending hassle later.

I will say this though: there is a whole ton of incentive for clang 
to become perfectly substitutable for MSVC. Just think of the Visual 
Studio annual licensing costs per developer seat, and you're starting 
to see how much incentive there is. I wouldn't be surprised if such a 
clang edition sees very rapid progress as soon as legally possible.
