Protocol Buffer for the payload?

[michcfr]

Hello,
Is there any plan that Homie uses the Google Protocol Buffer for the payload?
It enable compact mqtt messages.
This is for example what Sparkplug mqtt is using.

I don't know if it is a good idea, I just wanted to share and discuss about this opportunity.

Not likely. The current draft for version 5 doesn't change the format, and if anything introduces some JSON elements (single topic device description).

It was discussed however, here's my recollection of why not;

• not available everywhere
• has a steeper learning curve, so harder to get started with
• not easy to debug for user nor developer (because of its binary nature)

Thank you for the response.
The not makes sense.
May we get access to the draft for version 5? Thx
