The minimum required subnet size for consumption only environments is /27

The minimum required subnet size for workload profiles environments is /23

It is the other way around according to https://learn.microsoft.com/en-us/azure/container-apps/networking?tabs=workload-profiles-env%2Cazure-cliso consumption only environments need a larger subnet than workload profile environments.

It makes sense as a consumption profile will require a larger pool of IP addresses to allocate all underlying infrastructure, while there is a predefined number of nodes available in a workload profile environment.
