There was a period when one of the official bullet points for positive GOE on jump elements was "varied position in the air / delay in rotation."
It's not clear whether that was originally intended to refer to simple variations of air positions such as arm positions, as opposed to more full-body variations (as with delayed axels, split-flips, etc.). While that was on the books, many skaters did start including simple arm variations and were apparently rewarded for them in their GOEs, so de facto that did become a positive bullet point.
Some skaters apparently found that learning to jump with one or both arms overhead actually helped their jump consistency, so they started using those variations on all or most of their jumps and continued doing so even after the GOE guidelines were rewritten to remove that bullet point.
Which is different, in any case, from just "throwing" their arms up, maybe above shoulder height but not overhead, in an effort to hoist themselves up into the air in an uncontrolled way. That would not have been rewarded or have helped consistency.
The current, comparable bullet point is worded as "very good body position from take-off to landing." So that can reward either a standard air position or a variation, as long as it is performed with very good quality, not only in the air but also before and after.
Different individual judges might have personal variations in terms of how they interpret and apply these bullet points.
But it would be hard to argue, under the current wording, that lifting one or both arms should automatically deserve a reward.
