In documentation it's stated that:

A proxy will always collect data regardless of the maintenance type (including "no data" maintenance). The data is later ignored by the server if 'no data collection' is set.

https://www.zabbix.com/documentation/6.0/en/manual/maintenance

I was surprised to find that actually server also does the same - polls data from hosts which are in maintenance (without data collection)!

Was it by design all these years? Or it's some regression? (I've just have tested it in 6.0.18)
If by design, then why do we mention "proxy" in the doc statement?
I consider that as it's exclusively applied to proxies only.
If not - it misleads!

If it's by design, the statement should be rewritten to not falsely indicate that the behavior is specific for proxy only.
