USSSA jewelry change

[Little Jimmy]

USSSA has changed their jewelry rule from one that basically mirrored Fed to the one below...

2018-1 JEWELRY
Revised Rule 2.5:
"Sec 5. JEWELRY (Youth only - 18 & Under and younger)
Exposed jewelry, which is judged by the umpire to be dangerous, must be removed and may not be worn during the
game. Medical alert bracelets or necklaces are not considered jewelry. If worn, they must be taped to the body so the
medical alert information remains visible.
Players may wear unadorned items with no sharp edges or points, such as bobby pins, barrettes, and hair clips (no
longer than 2 inches) as hair control devices.
Coaches wristbands (play indicators) are legal but must be worn as designed.
Rationale for change: permits players to wear stud earrings, but continues to prohibit dangling hoops, rings, watches, etc

I'm wondering if this comparable to USA's, or any other organization's, wording. If it is similar, how do individual umpires, UIC's and tournaments deal with the "judged to be dangerous" part. A directive from the state or local UIC? Any problems with individual interpretations?
