Why are some domes gated behind breakthrough tech?

I see that there are domes that are gated behind breakthrough tech, and therefore i cannot use them in all my games. I wonder what the design goal of that really is? Is this something that would change in the future? I want to be able to play with all dome designs at my own discretion, afterall, it is a singleplayer game.

Because they have mechanical advantages over the standard domes.

1) Two spires each. This permits spire synergies like a medical center plus Hanging Gardens for spectacular birth rates in that dome.

2) They are very long, fitting through narrow gaps and helping extend passage-connected colonies to new deposits.

Yes, i know about the advantage they bring. Just like the larger domes you get for advancing in your techtree and unlocking them. I still think they should be available and unlocked in the last tech tier in the tree. Its not a multiplayer game, but at the same time, if i use a mod for it, i cannot earn achievements in the game. Not that it matters all too much for me, since i am soon done with all of them. I just want to enjoy those domes for the fun of it. I have actually never got the diamond dome before, and i have played more than 350hrs of gameplay. There are so many breakthroughs in the game as is.

Would you not be happy to see these domes become available in the techtree instead, or are you in favor of keeping them as is?

Its not a multiplayer

You keep saying this, but solitaire is not multiplayer either, but cheating in that game is still cheating. The keyword here is "game", and games have rules. I wish all breakthrouughs were available in all games (especially because I'm often unlucky and get crappy breakthroughs), but they're not. I accept that as a rule.

Adding it to the "normal" tree would be unbalancing; then 4 more techs would have to be added or one taken away.
