my read of the post from the @delegationtrust is that they want to delegate to support projects with a pretty clear viability for the platform. That application fee is a good way of separating the chaff from the wheat.
If your project is that uncertain at this point you are likely way too early to be applying. You'd be better to build interest and support in the community. Small delegations from a group of people also has the advantage of not putting all your eggs in one basket.
