This is what I've been reduced to

Animals climbing over a fence with no other blocks to assist them has never happened to me in vanilla.

It happened to me when I had overcrowded hare pen, they probably jumped on each other heads.

And, when the snow falls, then 1 block high fences can be climbed.

This was reported frequently in earlier versions of the game, but is it still true? In 1.20 I wasn't able to lure sheep into a fenced pen by putting a block right next to the fence. They would climb onto the block and stare at the grain trough on the other side, but wouldn't climb in and eventually wandered off again.

You are right that I did experience it in the past and not in the 1.22 version (as I have learned to build fences higher, so no case study this time  ).

But I may confirm that the block next to the fence does not work anymore, I had to add another block over the fence to make the trap working in this version.

I don't know when that may have changed, but currently all fences have the canStep: false attribute, which should make it impossible for animals to get out of a pen in virtually all scenarios, even if the fence is inset into the ground and there are three layers of snow (except maybe fences with shorter hitboxes which you probably shouldn't inset into the ground, but regular fence placement still works normally). What can get over fences is jumping players, possibly leaping entities (i.e. wolves, bears and locusts, maybe shivers in some way?), and maybe animals could also be pushed out in some cases of entity cramming.
