However, this kind of initiatives should come from Witness, from people at the top, who do novel things on the platform, and that this makes Steemit attractive. Because the issue I see is that if the people who are active here in Steemit and have some influence do not do it, how someone from outside will want to invest or develop a project here?

Totally agree with you @josevas217, witnesses and steemit inc. must provide input on this.
It is a large project and large investments that can possibly be financed through the Steem Proposal System
