While this is something that will resolve itself the vast majority of the time (with extremely rare, very isolated, very limited exceptions) if we implimented a policy like you are advocating then we would have to either pull down block hours and cancel flights or junior assign to CA positions for those meeting the 500/1 "company minumims".

The very rare couple of unicorns a few years ago when the entire pilot group was running around saying "I can hold Captain!" because 2 probies briefly got NYC88A awards was enough to get the tiger teams to pay attention. They were planning longer OE and other things, but just as quickly as it happened it was over so I suspect those efforts were at best backburnered or at worst scrapped.

But in any case, the only reason A positions would go to first year pilots is if no one else bid them. To change the possibly of someone under 500/1 from getting it would take other measures that would have their own negative effects. Not sure what the right answer for this is FWIW.
