Jon Hall used to love telling the story of the VAX backplane with the

in the board slots, which clever customers managed to damage and have
repaired with a non-glued-up backplane.
That was the VAXstation-11/RC. Marketing wanted a VAXstation with
fewer backplane slots that it could sell at a cheaper price. Rather
than manufacture a different board, they just filled the extra
backplane slots with glue to render them unusable. "RC" officially
stood for "restricted configuration", but we in Engineering called it
"resin caulked".
