Please take the time to fully watch the discussion of this topic by Dash Platform team during their Dash Platform Product Update S91 (see above source link and timestamp).
For the High Performance Masternode Solution there is talk of raising the Dash collateral to either 10.000 dash (higher TPS but more centralized) or 5.000 dash (less TPS but a bit more decentralized, but nowhere near as decentralized as having Dash Platform run on all nodes ofc).
Nothing is finalized, everything is still very much in flux. The Dash Platform team indicated feedback from the Dash community would be helpfull, so that is why i am kickstarting the discussion here.
Update 7th of October 2022 :
