Does defender support 4000+ user creation?

We need to monitor many smart contracts at once for our use case. But it seems like even the paid plan is not enough for that. So we figured, to prompt every user to openzeppelin defender and instructed them to get their own API key. In that way, each user gets to create 20 sentinels and auto tasks. And that's enough for our use case. We are expecting about a max of 5000 users. So we'll be sending many autotasks and sentinel creation requests from our server. We wanted to make sure will that be ok with defender products
