OK I don't actually know what that means. Anyway, hot on the heels of the 2.0.9x ZDoom series which also supports Strife, I noticed a file in /idgames called SvStrife Final Beta 1 which, according to the text file, is a PrBoom mod meant to emulate Strife, the source code to which was never released. It goes on to say
The whole purpose was to create Strife on this port so that maybe someday, the code can be ported to other ports like Legacy, Jdoom, and maybe Edge.
So there you go.
