An alternate implementation I was considering was to allow to delegate
facts, currently gathering facts with delegate_to: applies the facts
to the 'current host' or 'delegated for host'. This would solve not
only the issue when you want all host facts but also when you want
just a small group or single host:
setup: update={{item}}
with items: "{{groups['dbservers']}}
delegate to: item
This would gather facts for the hosts in dbservers group and apply
them to those hosts (not current) and make them available to other
hosts through the hostvars[] dictionary.
The force option gives you all or nothing, which can apply to some
setups but will be very hard to use on large inventories or those with
disconnected/slow hosts.
