Hello. One thing I noticed long time ago and that usually annoy me, it's the following:
Let's say I have 5 websites under multisite. If I delete the site with ID=3, the next site created will have invariably ID=6. Why can't the ID within be used if the tables were actually deleted?
If I have a multisite with 45 websites where a lot of them are deleted from time to time, I'll get I big gap of unused IDs.
Is this by design?
The only reason I could think of this having sense is if there is ANY poorly written plugin writing in the main wp_options table and not deleting its own information upon uninstall...
Hope to hear a clarification on this.
Thanks!
