Morrus, nice overview of the OGL--it's good to remind even WotC workers and executives about the practical thinking behind Open Gaming.
There is probably one very big difference now that would impact the chances of a new "glut". There are so few game shops anymore.
Iirc there's about 25% of gaming stores now as opposed to 2000. And the ones that are left are going to be very choosey about what to put on shelves.
You won't get a glut of print products because the stores won't stock them.
Digital maybe but that's up in the air. Digital only publications tend not to be as visible.
