I agree with this.

I only once recreated the configuration and this was when the device
was migrated from one switch configuration system to another. I could
have avoided even that by attaching a serial console and editing the
configuration using that after the update (or perfectly creating a
suitable new configuration before updating without applying it).

I think this depends on the target group. For very simple users that do
not read changelogs or release announcements, I would still recommend
that. Otherwise, I see no reason to not keep the configuration.
