Django is a generic framework. Those who use it to implement functionality are the ones who kill either the browser or their entire application. Applications must be written to meet functional and performance requirements of the project. When dealing with large tables, more effort is certainly needed when using the Admin. E.g. write custom ModelAdmins or admin filters that restrict the resultset size.
I don't think Django should automatically limit these queries.
