Description
Attrs has nice support for validation and conversion.
That same concept could/should be extended to post setattr() phase of attribute updates.
This would allow for publish / subscribe systems on attribute updates.
In theory this should be a trivial feature enhancement to allow an additional hook.

Research direction
Start by reading attrs' existing validation and conversion support and the related tests, then trace the post-setattr phase of attribute updates. Determine the hook's expected behavior for publish/subscribe use cases and add coverage showing when it runs and what is observable when the feature is complete.
