Obviously, given the low-level subject matter, this post wasn't aimed at turnkey engine users. In fact, people interested in this stuff are probably actively trying to be independent of those engines.

I will add that we probably need more people able to implement rendering engines. Having to chose between two corporate giants and suboptimal engines isn't ideal, neither for developers nor for players.
