I absolutely do not try to break my front tire loose swerving around on purpose !!! Just a touch of the rear brake and feeling how much traction there is before the rear wheel starts to skid is all that is needed to "test" and I do do that quite often. Recovering from a rear wheel skid without going down is nothing and just involves letting off the brake and re-balancing and steering out of the skid; way better then trying to recovering from your front tire going squirrelly on you and out to one side in a slide, that's potential face plant territory !!! At least that how it be with a two wheel front and rear wheel bicycle, on a trike with three point triangular stability its a different story.
