We somehow need to incentivize the proliferation of browser engines more than actual browsers themselves. Maybe an open design committee that could standardize modules the engines should contain along with calling conventions between them? That would encourage people to work on smaller chunks and not have to build the entire thing by hand. Perhaps browser engine prize competitions? If there were even half a dozen capable browser engines to choose from when making a new browser that were all accessible, then we wouldn't be in this mess.
