I am reading Cumulus PDK and Parachain documentations, and looking forward to converting our project to a parachain and join the Polkadot ecosystem.
However, I am confused regarding the parachain consensus mentioned in the documents. In FAQ section of parachains it is specified that "Parachains cannot use other consensus algorithms that provide their own finality", I am assuming it's about GRANDPA and not Aura or BABE. Refer to Parachains FAQ
Since Aura/ BABE are only block authoring side of the consensus, according to the FAQ mention above it should not impact the development of parachain even if I have a different block authoring logic.
Now, The document from Cumulus PDK, which specifies that the "Parachain will be able to use Aura, BABE, etc. (Not supported at the moment)". The focus is on the text in bold "Not supported at the moment". So according to Cumulus document I wont be able to use other block authoring consensus for the parachain node.
So if I want to join polkadot parachain ecosystem, can I use any consensus for authoring blocks as long as the finality is using the GRANDPA or is it not supported yet as mentioned in the Cumulus document.
