Description

There are certain use-cases where addresses will be auto-created and never have a direct binding created on them. Because of this they will never be auto-deleted. If a large number of these addresses build up they will consume a problematic amount of heap space.

One specific example of this use-case is an MQTT subscriber with a wild-card subscription and a large number of MQTT producers sending one or two messages a large number of different MQTT topics covered by the wild-card. Since consumers are never created on any of these individual addresses they will never be auto-deleted, but they will eventually consume a large amount of heap. The only way to deal with these addresses is to manually delete them.

We should have a way to tell the address reaper to skip the usage check.
