With the implementation of ADR0007 and ADR0010 some integrations have been left in a stagnant state. I can speak personally for the SNMP integration. There have been multiple PRs to improve reliability, standardize the use of unique ids and add better device support that have been closed unmerged due to the interpretation that any changes would require the integration to be rewritten to support UI configuration. Since this is a non-trivial task for an integration with as many configuration options as SNMP as well as its low usage rate, 440 active users, there isn’t much impetuous for a developer to rewrite the integration. Thus, we are left with an integration that continues to fall further behind the other core integrations.
Since these two ADRs are now over four years old, I propose that we review the remaining integrations that are not in compliance and remove them from core. I’m certain that the SNMP integration isn’t the only one in this state. Much like was done with the RPI GPIO support, they can be moved to a custom integration and then development can continue or not, but it’s no longer tied to core.
The other option would be to exempt them from ADR0007 and ADR0010, but I can’t think of other examples where we’ve done that and it’s likely not in alignment with the current Home Assistant direction.
