Camunda 8 custom forms not at all possible?

Thanks, @jonathan.lukas ,
How can I use other frameworks? If I use other frameworks, does it mean I cannot use tasklist? (I believe I read in the official docs that custom key forms are not rendered in the tasklist.)
And by “drive” the open-source project, which project do you mean?

I kindly ask you to take a look at this thread as well.
