Dialogue reads as if Thalyssra is very happy to join the Horde due to Blood Elf friendship. The Highmountain share an obvious connection with the Thunderbluff Tauren, and are almost one and the same. They actively want to unite with their kin. I am assuming the Zandalri wish to join the Horde because they need allies and there are other trolls in the Horde, so it's easy to find common ground.
However, the Alliance... aside from the Lightforge which is an obvious ally - not only Draenei but Turalyon has fought with them for a thousand years, so they are already pretty much in the Alliance - the other races are very controversial for the Alliance as a whole. The majority of them join due to relation to a lore figure (Alleria and Moira), and not necessarily because the people want it. The Dark Iron have a dark history, with a lot of conflict with the Alliance (and others) and so I could imagine there will be a LOT of people within the Alliance who won't be happy with a Dark Iron alliance. Then there's the Void Elves... which surely has to cause issue in that they are beings of VOID in a very Light-centric Alliance. Not to mention they will be near the Lightforge... you can't say there won't be members in the Alliance rejecting Void beings working with them. Plus, with the leaked dialogue from 7.3.5 it seems the Void almost harmed the Sunwell, showing the danger of it just existing near Light potent power sources. How could Anduin and others endorse this easily?
So, the point being, surely there should be some upcoming internal conflict within the Alliance with old enemies and 'dangerous' allies joining them, with Anduin's blessing. Perhaps there will finally be some story development around the Alliance and their values. That would seriously be welcome.
(And yes, I am aware that the Zandalari will probably have an issue with being in a faction with Elves, but I think they would probably accept it if they could smash some enemy elves while getting aid in the process).
