Is not normal for FOSS projects to get funding to use however they see fit at all, so the whole situation is "not normal" from the get go. Might be too long for your schedule, but at least they're getting funding from somewhere.

What planning do you think they engaged with before the funding? I haven't checked all the projects, but most projects seems to be "first time receivers" of this sort of funding, so unlikely they had much plans beyond "it'd be nice if we could eventually do this sometime" before the funding, and now they could hopefully feel a bit more stable to start doing some planning.
