I removed h3 pawn for 7-piece lomonosov position:

That was just the reason for my first suspcion too. If h-Pawn falls, fortress is fallen too as for Losomosovs in all cases I saw, and it looks to me like it has to be moved sooner or later, at last, when White's King can't move anymore,

[Nordlandia]

Now for something out of the ordinary
