Good question. We're participating on the periphery of the MLS discussions, mainly to try to encourage the MLS team to consider and support decentralised use cases. At the moment there's a temptation to go for a simpler approach which assumes there's a centralised sequencing server which solves all the races you otherwise get (and which have plagued us in Matrix whilst implementing Megolm). However, assuming a centralised focal point for each group conversation kills the whole point of decentralisation, so we're trying to ensure it's not designed out.
