I'm not sure why you find the idea 'restricting'
The goal is to portray the universe as it is. You want to portray the universe as it is observed to be from one very specific point in the cosmos. That is very clearly restricting.

I don't see why having at least some of that content represent the earlier universe
If some does and some doesn't, then that would be inconsistent. Also, programming it to represent things in the earlier universe would be MUCH more challenging and time-consuming than you seem to realize. A huge amount of work would have to go into it. I'm not saying your idea doesn't have merit, but I am saying that it is inconsistent with what SE has been developed to be, and that it would require much more work to implement than it's worth right now. Maybe in the future another version can be made with these things, but for the foreseeable future it simply cannot happen.

you claim that quasar formation is still possible in the modern universe. Considering that there are zero quasars in the volume of radius of 2.3 billion light years (a big volume), this is demonstrably false
Maybe you missed these points that I raised, which contest your claim:
Quote HarbingerDawn (

the nearest quasar known to have existed in the modern universe is only 730 million light-years away, which ceased its quasar activity only within the last 70,000 years
Quote HarbingerDawn (

quasars are simply the most dramatic examples of AGNs, which are ubiquitous throughout the cosmos. They will be quite plentiful even in an SE with a modern universe.
Quote HarbingerDawn (

)
Even if they were just as probable at all ages of the universe, you would still expect to find increasing numbers of them with increasing distance simply because of the rapidly increasing sample size at larger distances
So please tell me, if the nearest quasar to us is 2.3 billion light years away, how far away from THAT quasar is the nearest quasar to it? Are there any places we have yet observed in the universe where the density of quasars is a large amount per billion light year radius, which would be expected if quasars really were substantially more likely in the older universe? I'm not debating whether they were more common, of course they were, but I am saying that your logic deserves closer examination here.
Quote Ingolifs (

The conditions required for quasar formation no longer exist in the universe.
Please explain to me exactly what those conditions are and why they are impossible in the universe today.
