"2. Give the possibility to track the site submission status."
The main reason why this is highly unlikely to be implemented is that it would make it much easier for the spammers to target the ODP - they could see immediately when their application had been rejected and reapply straight away to another category or with their content on a different URL.
That would only be true if (1) approvals were immediate and (2) the status was updated in real-time. First, excluding any automation that might exist (e.g., scripts that check for a fetchable page from the given URL, content filtering of the site description, etc), the current editorial process (and any backlog) means reviews/approvals/rejections are not (typically) instaneous.
Second, there's no reason to have the status updated in real-time... As I seem to recall from previous discussion, there is no single list of site submissions. But assuming the data exists, I believe it would be fairly trivial to periodically (e.g., nightly) trawl the dmoz category hierarchy to consolidate such a list (into a database or flat file). The script to query the database would also be fairly trivial and have low impact (i.e., in terms of integration) to the existing dmoz site.
Note: the dmoz developers are welcome to contact me to discuss, recruit me as a volunteer, etc.
