Here's Sheldon Brown's warning:

"Warning: Since compressionless housing relies on plastic to hold it together, it is not as strong as conventional spiral housing, and should never be used for brakes! The loads applied to brake cables can easily cause compressionless housing to rupture and burst, causing a complete and sudden loss of brake function."

Beyond me why you'd chance a "sudden loss of brake function" just so your bike has Celeste-colored housing. Death wish?
