A Copy of Verses kept in the Cabinet, and only shewn to a few Friends, is like a Virgin much sought after and admired; but when printed and published, is like a common Whore, whom any body may purchase for half a Crown (Swift, Thoughts on Various Subjects)
99% of the small web sites which are built around MySQL don't need it.
I don't know about 99%, but there are certainly plenty of sites built by developers whose only knowledge of data storage is "database", and who therefore use one for everything, regardless.
I think the problem here is the razor-thin window edges.
The trouble is that the implementations of X seem to conflate the visible border of the window (possibly 1px wide) with the grabbable area that ought to cause the cursor to change to the "i can move this" double-arrow. That needs to be several pixels thick for most people to grab it. The designers of Unity and other windowing systems appear to place more emphasis on "looking pretty" than on "working well".
Any two can reproduce together, they can easily overrun an area.
No shit, Sherlock. Just like humans...
