Merge needed to be done one way or another, can't have faulting foundations. You also can't have development on more days if the foundation isn't done yet, you need to be patient and wait for it to be built first before you move on to other parts. So while it is not fun to wait, it is very much a needed process.
Its better than having the merging be spread out, causing more bugs, waiting longer for features to be fixed, having just this mounting slog to keep going through. Instead its legit getting all done in one go!
We're almost there, just please lets all settle in for just a bit longer
