Using DragonEgg was the lesser evil in the past and it almost stopped serving a useful purpose.

Your contribution is welcome.. but my feeling is that DragonEgg was just an intermediate solution in the past for shortage of LLVM frontends in the past.
Lately it served little purpose and it was effectively obsoleted.
