Integration Queue

I would like to ask if this feature would be something of interest for others:
We use different types of Integrations (mainly MQTT, HTTP and InfluxDB).
Especially for the HTTP Integration, we have sometimes the problem, that the endpoint (which is not controlled by us) gets down for some minutes or longer. Now those messages which where received in that down time are gone. So my feature request would be, to integrate a queue, e.g. for a configurable amount of messages (FIFO), to store them (maybe in Redis???) as long the integration endpoint is down, and deliver them when the enpoint is up again.
Any comment on this is wellcome! Thanks!
