There are kind trans folk involved with the FSEP project, from the approval of the project, to feedback on its design. There are also cis folk, queer folk, Black folk, white folk, Muslims, Jewish folk, Buddhists, atheists, etc. It's a big effort.
A big part of the project is collecting feedback and input, because this is far too important to get wrong.
So the initial design is being done in the open. There are a number of things that need to be improved before this is ready for prime time.
