My understanding
Please allow me a few more comments, because people seem to wonder about this proposal. I might be off, but @Nagalim can correct that.
In normal times, doing a grant could be the way to go.
Normal times mean thereās enough time for the grant to pass.
But these are extraordinary times with a suddenly surged demand for NBT. FSRT was created to deal with that.
Soon the FLOT will be ready and will have some discretion for making decisions regarding liquidity managagement.
As it happens, the FLOT is not ready yet and for that reason this motion was created to put the decision in the hands of NSR holders - this motion allows ongoing NBT distribution without having a grant pass each week!
Thatās one of the important aspects of it.
Everything works as designed 
Forecast
Grants with similar terms like this motion need to be a part of the liquidity portfolio to save the FLOT and FSRT from being regularly involved in liquidity operations. They are a line of defense if thereās extraordinary need.
That seems to be similar to the not so decentralized liquidity operations Nu initially had with @KTm and @jmiller operating bots on the exchanges and offering buy and sell side liquidity.
The big difference is that this is a motion to inject NBT into the market and put the proceeds in the hands of Nu, but not to put the proceeds on buy side.
The liquidity operations on T1-2 stay as they are: Nu incentivizes liquidity providers by compensating them for their effort and risk providing buy and sell side funds.
This type of motion allows injecting funds from higher tiers (here T4, but T6 is possible as well) into the lower tiers.
Similar motions/grants for the buy side could be made to deal with the need to contract NBT supply.
Having a buy side and sell side operation at the same time, siphons both NBT and BTC from T1. Depending on which side runs dry earlier, itās clear whether NBT supply is expanding or contracting and which grant needs to be renewed.
The cost for not deciding whether to run only buy side or sell side is that additional costs for exchange fees and tx fees need to be paid as well as the exchange default that is extended to more funds (two sides instead of just one).
I would advocate to have buy and sell side operations at the same time, because that saves the FLOT or FSRT a lot of work.
If the FLOT/FSRT were required regularly (and not only in extraordinary times), the compensation the members of these teams request are likely to be higher than the exchange and tx fees.
