Reading the announcement it seems their biggest concern is privacy/security from a NS perspective by using Indian SSL key servers instead of ones from other countries, not actually the engineering task of implementing every browser standard from scratch, plus other nicety features like signing documents within the browser.

At this point in time I think a large heavily funded government project is the only way we are going to end up with a fourth working rendering engine but no one wants to put in the resources because a sanitized Firefox fork is usually good enough for nearly all applications that need a browser of some sort focused on privacy and security that people have already spent way too much time on to make standards compliant
