I'm assuming you're going to assign a new host with the retired's host ID. In this case the data will be overwritten. If you have any issues, please report. Thanks!

Hi Frank.
This is still in the works, but the right way to retire a host
is first to put it into local maintenance (there's CLI for it
and hopefully by 3.4 GA we will do it when you use the UI to put
a host into maintenance).
Once the host is in local HA maintenance, stale data is no longer
reported, which should give you a valid status report.
Just FYI, we prefer to keep the original data for forensics, as
HA behavior is sensitive and we'd like to be able to trace back
in case of a failure.

[Users] Remove host from hosted-engine setup
Hi,
I've retired a host that was part of a hosted-engine setup. How do I
remove this host from my hosted-engine HA setup?
I have retired "host01" and would like to remove it completely:
