Pawns seem to gain a bit in value if more than eight of them, at least here in your position Uri. My Shredder GUI will not accept the 16 black pawns but Stockfish in "DOS mode"will calculate with it. I don't know if the board is displayed correctly but Black has pawns on both the seventh and sixth row. Stockfish at least with very little hash in default setting can't get through it it seems: score stays at about 3000 centipawns
I don't really know what causes it but I don't see it in simple CLI output with my own TDM-GCC compile of development version Stockfish from 05-24. Code is default Stockfish from that date (so only Marco's latest changes not included).
Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

I am not sure that this one is a mate. It seems to me that the pawns can be set up to support each other to make a pretty impenetrable wall.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
I am practically sure all the pieces against 16 pawn is mate.
No mathematical proof but a possible plan that convince me that it is mate is simply to trade pawns and KQRRBBNN vs king and 8 pawns is a simple mate when the pawns are not advanced.

What if the opponent is very determined not to trade pawns, but to try to form rammed zigzags instead?

I do not think that black can prevent trading pawns.
White can for example put all the pawn in the 3th rank and prevent black to go to the 4th rank without white forcing a trade and if black move only with the king then white can play e4 and if black replies e5 then d4 trade pawns and if white does not play e5 then white play d4 with the plan to trade pawns later by d5 that threat both e6 and c6.
Note that even if white has only one pawn to support trades and black has 2 pawns to prevent trade white can use another piece to help so this structure is not enough for black to prevent d4 with trading pawns and

black need this type of structure and I do not believe black can force it and even this structure may not help black.

I even do not think that this position is a draw.

white can have a plan to sacrifice the biahop for 2 pawns by Bc3 Qd2 and later play b4 and continue trading pawns.

Both you are Uri are obviously right.
Your explanation is the simplest.
It makes is crystal clear instantly that black is lost.
If I were black, I would try "the mother of all pawn storms" to see if I can promote.
No real chance it would work, but it is the only sensible attempt that occurs to me.
