This implies that an account with good standing in the long-term was not previously taken into account.
Exactly, everyone got the same treatment. The change is that they're giving long term publishers better opportunities to explain their situation.
What if you're an honest but amateur un-tenured publisher and break the TOS? Most people don't read the TOS, any TOS. It's a common activity, everyone is guilty of it. Everyone is guilty of not reading some rules here and there. One could say their error is probably the same as the tenured publisher's error. Should the un-tenured have recourse to better opportunities to have their explanation heard?
