but did Luxemburg deny the need for a vanguard party altogether

from my understanding she was opposed to that type of centralization, from the organizational questions of the Russian social democracy:

Granting, as Lenin wants, such absolute powers of a negative character to the top organ of the party, we strengthen, to a dangerous extent, the conservatism inherent in such an organ. If the tactics of the socialist party are not to be the creation of a Central Committee but of the whole party, or, still better, of the whole labor movement, then it is clear that the party sections and federations need the liberty of action which alone will permit them to develop their revolutionary initiative and to utilize all the resources of the situation. The ultra-centralism asked by Lenin is full of the sterile spirit of the overseer. It is not a positive and creative spirit. Lenin’s concern is not so much to make the activity of the party more fruitful as to control the party – to narrow the movement rather than to develop it, to bind rather than to unify it.

she also talked about it in "The Russian Revolution" after they took power, chapter 5 + 6 were the relevant sections in that

Fair enough, I was basically just commenting because you invited feedback, though I’m sure you know that.

no worries, it's welcome!
