Following up on a comment I'd originally made, I have enough reputation here to see and do everything that anybody short of a moderator can see or do.
When I look at a question that's been closed, I normally see a banner that indicates why it's been closed and who voted to close it:
In particular, it indicates this:
(Viewable by the post author and users with the close/reopen votes privilege)
However, when I look at this particular question, that level of detail is missing from the banner:
Nor is the parenthetical information about who is allowed to view the details shown in the banner.
The only difference between these two questions is that the one that shows a banner without detailed information is a question that originated and was migrated from a different site before being closed here.
This is the first time I've noticed this.
Coincidentally, between the time I'd posted my original comment and this reply, I came across another closed question that had been migrated from elsewhere and then rejected when closed by our site:
So, if it's a migrated question that's been closed, nobody (moderators aside, apparently) gets a banner with details. I can still see some additional information by looking at the timeline, but it's not the same as with questions that have not been migrated (and then rejected).
It's not clear to me if this is intentional or not.
From my personal perspective, the fact that it's been returned to the original site is sufficient banner information for me. Note that it's not possible to reopen a rejected migration—so knowing the details can't matter for that purpose, and it can't be updated to make it on-topic as that part of the regular banner text says.
On the other hand, I can't see why providing more detailed historical information would be a bad thing.
