Are those project up for takes or designed specifically for some program?
Sorry, I don't quite understand your question.
A project idea has no value, is null, unless it is turned into a project.
To turn a project idea into a project you need to find first some interested mentor,
then write a good project proposal, and if this project proposal is accepted, then
you have a project. You can submit the project proposal to GSoC (next year)
or to Outreachy (next month) if you are a woman or some other endangered
community, or to other sponsorship programs.
I am not sure whether I answered your question correctly.
