Comment (by Rodrigo Vieira):
That's a pretty old ticket, but I'd love to give this a go, I think it
could be a nice QoL improvement.
For example if we try to delete a model with thousands of children (which
in turn may be their own children), not only the page may take minutes to
load and overload the browser, but the delete button is pushed **all the
way to the bottom**, so the user will have to wait for the page to load
and the browser to render everything to access the button (maybe even
moving the delete button UP, after the summary, could be an improvement?)
I like @terminator14's idea above of having a limit of, say, 100, and then
we render something like `...and N more` and the end. Probably the
cleanest solution is to tweak
[https://github.com/django/django/blob/main/django/contrib/admin/utils.py#L127
get_deleted_objects] to truncate the list and do some math to know which
number to put on the "..and N more" text.
One thing I'm not sure is where such config value for the limit of nodes
to list should reside. Would we expect for it to be overridable via
settings.py?
