[Star Trek/Warhammer 40k] The Tau come to the Federation's galaxy. Do they assimilate, or join any factions?

They send a diplomat telling great things if they join the Tau for the greater good.

Naturally, 95% of everyone they meet say "na, but thanks for asking" or "We already with the Federation" (assuming they start in the Alpha Quadrant).

Then said 95% find drop ships all over their plants and some incredibly impressive weapons shooting at them. Then the Federation relies they don't actually have that many warships.

I think they start with minor races who only possess 1 or a few planets and don't go after someone big like the Klingon or Romulans right away, they need some strongholds and cannon fodder for the Greater Good first.
