Users are currently only able to see concurrency in use by themselves. This works fine when users have a dedicated concurrency pool, but when they share concurrency with sibling accounts, it is not clear what is available at any given time.
For instance, say user grandparent has subaccounts child_1 and child_2, and has 10 concurrency slots. When child_2 is using 8 of these slots, child_1 does not see their available concurrency change.
For planning and diagnostic purposes, it would be helpful to see actual available concurrency, rather then concurrency if others were idle. The current situation is confusing and unhelpful.
