Other than the pointless flaunting of privilege in this ... I think keeping engineers very close to the project is usually a sign that not all is well with the project.
I read that as "We can't let this project out of sight of the engineers ... they need to be able to make changes on a day to day basis, from direct observation."
That these engineers would be moving in breakneck speed (ha!), to fix whatever they see in person rather than the usual separation of concerns in testing mission critical software.
Through those glasses, it is roughly an admission that it is in "patch everyday" phase of development.
