Mesh paint mode - option to *require* CTRL be held to paint (the original behavior)

There are options in the Editor Settings to *require *that CTRL be held when using the Foliage made or Landscape mode:


Can we please have that option for Mesh Paint mode too? You used to have to hold CTRL by default, which was good. But as it is, I keep messing up my nicely painted work when I try to move the viewport camera with the left mouse (using non-WASD movement).
