One thing that bothers me about this moment being the impetus that drives the "arkcon pathfinder initiative" is that it is very late in the game and we could most certainly not see hanar, drell, quarians, or geth in Andromeda.
We will see the krogan because, genophage or no genophage, they can still breed and thrive in Andromeda concerning themselves with building a home as opposed to fighting. I have not played the trilogy in over 2 years, but was it not said that with enough time- which we are being given in this new setting and I suspect allows us to build that huge citadel-like replica in Andromeda possibly for a sense of normalcy and community (I do not think that is the actual ark that exits the Milky Way) - the krogan can defeat the genophage on their own.
However, the drell and hanar can be doomed in that hanar diplomat mission. The quarians that participated in the conflct with the geth most certainly perished. While there are certainly stragglers or exiles, would the council even desire to planet hop here and there to pick up enough quarian stragglers for the ark mission. And even if we did invite these stragglers and exiles I doubt they would join, especially if the geth are on the ark (were chosen).
I think BioWare will drop the drell, hanar, geth (definitely) and quarians from participation in the ark if the decision is made post-Thessia.
