Precisely. This is also the source of the problems with VR where the viewer can get sick of these. Me too, i hate this blurring, and the higher the coefficient for the equation the better the blur gets reduced.
Yes the side effects upon camera movement will result in aliased content showing up since the antialiasing get’s seriously reduced on high values. On a desktop monitor this can be witnessed.
Then it finally serves it’s main purpose. Anti ghosting is only a side effect under given circumstances, but was not among it’s primary function 
No don’t use the tonemapper sharpen on scenes where high contrast can happen. It is best used on low contrast scenes only! You should use only this sharpening that excludes the high contrast areas, thus providing you the sharpening on the fine details only.
If you allow me to recommend this combined solution for your VR project, then please by all means try it! In VR you will find to be less annoying to have a little aliasing artifacts, so you can just go wild with these values and apply strong effect for any or both equations. The resulting deblurred screens expected to cause less sickness, but let us know what are your experiences!
