If you are cleared for an approach into an airport without radar approach
service, the entire airport get shut down to IFR traffic until you cancel
IFR, so spacing is a non-issue.


That's not true. You can have multiple aircraft cleared for approach at
airports not served by radar, you just have to provide separation. Radar
isn't the only way to separate traffic.



If you conduct a visual approach into a non-towered field and do
not cancel IFR, again the airport remains shut down
so spacing is a non-issue.
