I try to avoid using additional bridges as much as possible.
For example, I use Philips Hue lights, bulbs, and sensors without a Philips Hue bridge. It works perfectly for my needs.
One of the advantages of using additional bridges is that firmware updates can be installed on the connected devices. Hopefully, this will soon be a thing of the past once Homey allows OTA updates for Z-Wave, Zigbee, and Matter devices.
Edit
Inspired by this post, I created a poll. My main goal is to hopefully get more votes, but not to start big discussions. I would appreciate it if you would all give your vote.
