If a crew called established before being within +-5° during an LPC it would trigger a repeat if I was examining with a discussion about CFIT thrown in for good measure. Likewise if they deviated from +-5° during the approach and continued while not being visual, or went below any hard minimum altitude.
If a crew obeys the rules in the sim and then breaks them on the line, they’re asking for trouble in an environment where a repeat / retest isn’t an option.
