Yes, the Standard Skill List includes a “regular” mount and riding in a straight line. Then again, a beginner rider in a Street competition might do the same thing. In fact I think I’ve seen it done (among other skills). One must allow for generic unicycle skills in any of these competition forms, though they don’t necessarily need to be part of the levels.
Sometimes the Street “community” starts to sound a little snobbish. “Excuses me, but that’s not Street.” That’s all a matter of opinion at this point, and there will always be crossover. Remember, a 360 unispin was Freestyle first, then Standard Skill. Only now is it also Street! 
Anyone interested in this project should also consider making it a part of the Skills System being developed for the USA inc. by Carol McLean. I tried to find a thread dedicated to that topic, but not sure if there is one. Read down this one to find out more:
The advantage to working within that system is that it covers the duplication in the beginning rider stages. Also it is much more likely to be adopted by the USA (and later the IUF) as an official system!
