flexbox, grid, table,etc. shall be values of some 'flow' or 'layout' property as they define layout model of element's content. 'display' values shall just define requirement of the element to its container: display:inline, display:inline-block require flow:text container and display:block require flow:vertical, flow:horizontal wrapper. So it shall not be display:inline-table, display:inline-flexbox and the like.
