In reply to Erik Joling.

Thanks to everyone for answering the questions.

The only followup I have is the overwhelming recommendation not to use the plugin on production sites.

It would seem worth the risk at this point in time to use the latest and greatest code release. This way I can leverage ASAP, the advantages to a rapidly improving product.

Beyond the usual risks of using beta software (is Gutenberg in the repository actually beta?) Do I have to worry about an odds on chance of a catastrophic crash or security breech?

Based on the Gutenberg plugin page, it seems that there might be an even better chance that the latest repository version could reduce risks.

Cheers
