Hello. What i think it's a good move since i don't think Gutenberg abandon any time soon as everyone jump on it and a new generation of page builder are based on Gutenberg. I Din't like two things, the first is divception of page builder and gutenberg page builder it's tons of div in div in div in div and genrally with clean coding we can achieve way better coding semantically. (i don't like bootstrap for the same reason.)

Secondly Redux have a huge database for sure it's include most of the other gutenberg page builder inside like kadenze and much more. So the user will end up with tons of gutenberg addons which is as bad as multipurpose theme with 30-40 plugins. Still something like that can't work fast enough on most of the cheap hosting plan... what leads people to spend a fortune of money on cloud hosting, wp managed hosting, CDN, and all sort of optimization.

This could be more simple, more lighweight and semantically well coded (ACF, CPTui etc...) even on a website based on wordpress.

The two one for now playing the game close to the perfection is Oxygen Builder and Pinegrow (with WP) but yes you need to have a minimum set of skills to work with those tools. It's not for everyone.

After tested redux i would not go for it. because of what i mention bellow.
