The Meta Box blog contains several articles on the topic of Gutenberg and the Meta Box plugin (such as https://metabox.io/gutenberg-update/ and https://metabox.io/disable-gutenberg-without-using-plugins/). My preference is to use Classic Editor. I usually disable it with the Disable Gutenberg plugin (https://wordpress.org/plugins/disable-gutenberg/). However, I have recently returned to using Meta Box AIO after a gap, and seeing all the different articles with different updated dates has caused me some confusion, not to mention all the updates and changes to both WordPress and Meta Box AIO.
So, now what I would like to know is as of the recent updates with WordPress 6.8.3: is it still safe to completely disable Gutenberg if I want to use Meta Box AIO for my website?
In other words: will I miss out on any features that Meta Box has specifically for Gutenberg or will I harm my website performance and speed in anyway by opting to use Meta Box AIO and Classic Editor?
