While I understand that we want to feel an effect from bonuses gained from ethos, civics, techs and leaders the amount of various bonuses we can stack is upsetting the balance, favour the player too much and makes the game boring once we pass a certain threshold.
For example, it's too easy to stack happiness and forget about rebellions entirely, even as a slaver empire. For a player. AI never tries to minmax modifiers because of obvious reasons, which creates a situation, where AI empires that could've posed you a challenge in mid and late game are screwed by early game revolts due to inability to manage unrest and happiness. Players on the other hand continues to accumulate modifiers they want and reap the benefits easily avoiding any negative reprecussions.
A player can easily stack unity civics and building, get to the third point of ascension perks in 30-40 years (maybe even faster), grab +200 naval limit, then get rid of pacifism in favour of militarism, change civics and go roflstomp advanced AI on insane.
I can continue listing different examples of players optimizing their empires, but I think you got the point. What I believe we need to enjoy the game more is generally weakened positive modifiers and probably a bit stronger negative ones. Not every modifier needs to tweaked of course, let slaves provide 10% bonus output initially, but cut the bonuses from civics, techs, governors, edicts so that a slaver empire won't have a 50% bonus to minerals so soon. Maybe making modifiers stacks in a multiplicative manner could also help.
By making the power creep more subtle and steady we will achieve two things: first of all, players will enjoy the game more, builds will become more balanced and achieving the supreme status in the galaxy that causes eventual boredom will become harder, secondly ascensions and megas could be moved to earlier phase without upsetting the balance and Megastructures will actually matter.
