There was always a preference setting to switch the buttons if you wanted. The preference setting is still there. Along with most of the “keyboard shortcuts ... and other nastiness”. The one important improvement I have found in this area is separate keystrokes for select-all versus select-none, as opposed to the old single-keystroke toggle. I never understood the left-click/right-click issue anyway. In apps where you left-click to select, selection is a tool that you have to switch to first before you can use it to change the selection. Then you switch to a brush or whatever to do things to the selection. In Blender, selection is not a tool, it’s something that’s always available. Hence the usefulness of a dedicated button. For example in weight-paint mode for animation rigs, you left-click to apply the brush to adjust the weight for the current active bone, and you can right-click on a different bone to change to adjusting the weights for that, and then keep on painting with the left button. No need to keep switching tools at all. Unless you switch the selection preference to left-click. In painting modes, left-click still paints; only now you have to do control-left-click to change the selection.
