Overall I think this is as positive - protecting the system from being hit heavily 24/7 and with multiple agents from some users might make the system more sustainable for a wider population of users.

This one thing that bugs me is the visibility of how far through your usage you are. Being told when you're close to the end means I cannot plan. I'm not expecting an exact %, but a few notices at intervals (eg: halfway through) would help a lot. Not providing this kinda makes me worry they don't want us to measure. (I don't want to closely measure, but I do want to have a sense of where I am at)
