LGTM. Seems to be working fine from my testing, but I'll daily drive it for a while after it's merged to v0.6.

Before I merge, could you add changelog entries for setupopts and the removal of nvim-compe? Would also be neat if you could describe the usage of setupOpts in the hacking section of the manual - but that's not critical.
