Fresh Install if ELK 7.10 floods deprecation log

Originally posted here: Fresh Install if ELK 7.10 floods deprecation log and at the recommendation of @DavidTurner creating a new post here...

A fresh install of ELK 7.10 fills the deprecation log once Kibana is installed.

In the JSON log they are de-duplicated, but in the plaintext log they generate several per second.

Note that originally I had an install of the "OSS" version, then completely removed that, and switched to the main version which generates many more indexes that start with a dot (.). Examples include:

.apm-agent-configuration, .apm-custom-link, .async-search, .kibana_1, .kibana_2, .kibana_task_manager_1

Hi Jacob,
Are you running 7.10.0 or 7.10.1?
Do these errors appear only when you use a specific Kibana application or independently from what you are looking for?
Is there any chance that a parallel but older Kibana server is running in the background?
I've tested locally with a fresh 7.10.1 installation of ES and Kibana, but I can't see any of those deprecation logs.
Have you configured anything in particular? installed third party plugins or using an external application that uses ES?

Are you running 7.10.0 or 7.10.1?
--As of right now, it's 7.10.1 (I ran an update on Saturday, so I'm not sure if what I started with was this version, but the issue is still happening.)

Do these errors appear only when you use a specific Kibana application or independently from what you are looking for?
--These errors were (and still are happening) with ONLY a bare ElasticSearch and Kibana install. I hadn't even configured data inputs at that point, although now I have added them,

Is there any chance that a parallel but older Kibana server is running in the background?
--There is only one version of Kibana running in my environment.

Have you configured anything in particular? installed third party plugins or using an external application that uses ES?
--As of right now, I also have Cerebro, Graylog 4 and Grafana. None of these specifically reference those particular indices from what I can tell. That being said, when I tore everything down and started fresh, all I had was ElasticSearch and Kibana, and those issues were present with literally nothing else installed.

My logs now look like this:
