Too short connector.

You've sent the same claim to my eMail, with pictures. Your pictures clearly show that the connectors were contacted well below the end of the open surface. It is designed with lots of headroom, and there is not a single reported problem with it. Just because other companies do it differently, it doesn't mean it's better.

Your claim that flully inserting it makes it "not work" does not support your theory that the contact area is too short. It merely shows that some slots are designed in a way that a fully-inserted card will push contacts aside, lifting them from the contact surface. While this is an often-observed problem in the Amiga world, it is not caused by too short contact areas, so it also cannot be remedied with longer contacts. If the spring contacts don't push on the contact areas any more, there's nothing that the Zorro card itself can do.

That said, what you're describing does not apply to the original Commodore slots, made by Foxconn. However, I do know of Elbox daughter boards that display thie behaviour. It is easy to show that the behaviour is not a property of the Buddha, but a property of the Zorro slot that Elbox has chosen.

Indeed, little known facts. Anyway not your fault.

A more slim PCB may help with those sockets with obviously non-standard, improper dimensions or bad manufacturing quality affecting a fraction of customers.

I'd end up making lots of different versions, possibly making compatibility worse for many other customers. It's not been a problem all these years, and Amiga hardware has always been "wiggle a bit before you acceopt that it doesn't work"
