My apologies if I've stepped on any toes. AFAICT, these were released.

I will continue with them (and a few others) to 25000.

No problem. If you have a good idea of which bases you will be running to n=25K and can post them here, I'll go ahead and reserve them for you to avoid any duplication of work.

I am reserving Riesel and Sierpinski bases 322, 328, and 422.
