Not to put too fine of a point on it, but Team Update #11 provides an example of "what will be considered safe," not specific regulations on what must be done. The example shows one way to cover the three things that I would consider important:
- protection from ejected debris in the event of prop failure
- protection from ejected debris in the event of FOD ingestion
- protection from insertion of body parts (fingers, toes, noses, etc)
The update leaves enough room for teams to come up with alternate designs for their protection methods. As long as that alternate method covered the three items listed above with equivalent or better levels of protection, then it would appear there is still some design flexibility here.
