Hello @novocadian,
The HF20 Survivor badge is a nice idea, but what would be the exact criterion for its attribution?
Moreover, to send hundreds of thousands of additional notifications would be extremely RC consuming. These are the main reasons why we did not do it.
Anyway, feel free to make new suggestions as you did.
Wish you a good day.
Perhaps when awarding another milestone (which would indicate activity) one could be awarded the HF20 Survivor Award if the account was created prior to HF20 release.
This would conserve your RCs at least.
