Help identifying still open projects on https://www.x.org/wiki/SummerOfCodeIdeas/

Hello Karol and other members!

I see that on  https://www.x.org/wiki/SummerOfCodeIdeas/ there are lots of
compiler related tasks but most of them seem very old.
Are they still relevant?
Kindly provide some details.

Sincerely,
Vivek
