The only occasions I check someone's grimoire is if run into someone very low level while on patrol, just to see if they might be new. I like to see new players entering the game. Another time is if I get matchmade with someone in a strike weekly or POE and they seem to be making bad decisions. If they have a low grimoire then I know that they might not have the XP and I'll need to step it up. Not because they need carried, but because as a team we need to fill that void. Example. Earlier today I was farming 28 POE. 2 games in a row, different players, one of the other guys seemed completely lost, like he didnt know what to expect or what the objectives were. Both of these players kept being killed and did not anticipate targets or mines. They both had low grimoire. 34s with barely over 2000. Both were also even for a 28 poe seemingly under equiped or just simply made bad choice in gear and or weapons.
