IMHO it's not a bug, since there's glShaderBinary call. We can assume that
there's some
performance critical GLESv2 implementation that doesn't allow one to compile
shaders "online",
but provides an "offline" compiler and the user is only allowed to use compiled
shaders.
However, I don't know if such implementations/GPUs actually exist.
