It is an excuse to delay the rating upgrade. More accurately, it was to chill investment interest by signaling the upgrade will not happen anytime soon, not until Tesla has a more diverse offering of models. As if a ratings agency knows how to run a car company better than Elon Musk.
Whenever such an organization makes a decision for obviously wrong reasons, there is generally internal dissent or pushback on the decision within the organization because it makes them look foolish. The internal pressure is probably building for them to upgrade Tesla and the fact that the Tesla Semi is not a light passenger vehicle doesn't really matter, it could give them the excuse they need to finally upgrade Tesla, without looking like they are backing down. As it is, they look increasingly foolish every month they don't upgrade.
Was the same thing when Tesla was being included in the S&P500. S&P published a ridiculous “not yet” blog article.
It is difficult to imagine any other reason for these delays other than large entities who these agencies are beholden to are not positioned appropriately to benefit.
