Adding on the Q17/27 also has greater frequencies than the Q25/65 which is sorely needed in the north.
Q31 seems like another throwaway route to fill in the missing gaps though I do like that there is another north-south option that doesn't traverse through Flushing. It would make more sense to have that route coming from 162/164th St but that would come at the cost of the Q65 no longer serving Flushing and that was a major issue in the original draft.
It made no sense to have the Q44 be the only Flushing to Jamaica LIRR route, the curtailing for the Q20 shows that the MTA doesn't know what people in that area are using it for. Honestly, it makes more sense to have the Q20 be the route going east of the LIRR than the Q44, I can't imagine most of the people getting on at Jamaica Center and Merrik are going to the Bronx.
The Q25 really needs to go back to Jamaica LIRR, the way they want it to be a Limited route, yet a local version of multiple rush corridors, and not even provide a service increase. That route is doing way too much for almost no benefit for the people it's expected to serve.
