For years thargoids were extremally shallow content, just "go to 1 place in whole galaxy (ok, after some time to 2 and finally 3 places), hunt signals thousands ls away to hunt ONE alien in 1vs1 duel".
So now I have no problem with focusing on AX, adding new activities, which can help war effort (personally I love fact, that pure combat isn't only option now), modules, which put entry bar slighty lower (moar dakka, gimballed AX dakka and better scanner is first example, another can be planetary CZs which we had for some time, much easier due to no swarms). Currently AX in my opinion is much more better, depper, and more diverse. AX folks deserved for it. (and all other people, since as I said- now you can support humanity with trade, passenger runs, SaR and even sampling). And to be honest, each new thargoid ship add more interesting details and mechanics, than any ship for players.
Even not saying, that old content still exist, in peak moment thargoids took only 1% of systems at distance of 250ly to sol. I still can do everything, what I did year ago.
