I agree, just a bit jaded. I've experienced such discussion about previous TC buffs, > 5 year truces, horde nerfs, primitive ship nerf, and movement lock in the past. We know how those went, even when the change objectively did not align with the stated rationale for it (truces, ship nerf, TC buffs, move lock).
Of course I'm extremely dubious about how this will work in the new world. They've had zero regard for gutting gameplay in favor of...nothing but waiting there in the past, with no need to do so. Then we got that out-of-touch nonsense alteration requiring ADM 8 unless you buy DLC to attain still-slower times to actually play the game than pre-El Dorado. So government reforms there have a potential to go pear shaped super fast, further stripping agency compared to now. It might get better too though, especially if they finally drop the "must have Euroborder" and "arbitrary tech boost" from the game and make progress contingent on agency.
I'd like that, but I don't anticipate it happening.
And certainly, I'm not intending to squelch interesting discussion. I'm just pointing out that some things you can realistically expect to see happen (progression speed of reform for government), while others are unfortunately unlikely to change regardless of what you point out in advance (infamous example is the game lying about the reason you can/can't take provinces in peace deals - identified in public beta for common sense DLC and still in the game right now, years later).
Native Councils don't have Dharma govt reforms, and the other primitives will probably use them like everyone else (as in, it won't change the gameplay issues they face right now).
