People have been working on bikes inverted, usually drive side facing you, for many decades without the benefit of a work stand. As long as you have decent chain tension, it should not affect your results, and you have complete freedom to run the crank. I also true my wheels that way. V-brakes, I service with the bike upright because the brakes and bosses face up in back, and forward and up in front. But even that way, I use the table, because it raises the bike to perfect standing work height. Handlebar work I do with the bike on the floor, leaned against the table.
