I mean... okay, but no matter how much you believe in it, it doesn't make any sense. This would offer no advantage over conventional satellites for this application (ie it would be similarly terrible for it).

Are you thinking of something like this? https://en.wikipedia.org/wiki/Kinetic_bombardment#2003_Unite...

Again, you probably wouldn't bother with VLEO for that, too much extra complexity with no obvious advantage vs VLEO.
