Eh, I wouldn't consider any of these deal breakers for many mass hosting situations. I don't really want people uploading zip files to waste my premium NVMe, so I'm not really concerned if there's issues with it. People could always use the old trusty method of FTP. Cpanel has a great file manager, but there's a dozen other panels that have crap file managers, it's not a new thing that they be imperfect.
I haven't dealt with phpmyadmin much yet, but I also don't use it very much for importing in other panels either because they all have similar issues. For exporting it's fine, but phpmyadmin for imports, nah never. Other tools I've used for importing SQL to sites work great, and ssh import has worked great, that's the way I've been doing it for decades, I don't expect enhance to be any different.
Lack of firewall UI doesn't affect users, so I don't see an issue with it being needing worked on through command line. In cpanel I can login via ssh and whitelist an IP faster than I can login to the cp and click around to the CSF firewall section, look around for the button/settings/etcetc. How often is firewall config change really needed anyways? Hardly ever.
SSO works perfect in Apache from what I've tested so far. I agree OLS needs work, but SSO isn't as critical to me as getting persistent config and htaccess updates without restarting the container - those are much more critical imo.
Logs are in the roadmap next month, really looking forward to that, but I have found alternatives that are working good for troubleshooting in the interim, so it's not a deal breaker for me and far from excluding the panel from production use.
For the rest of the gripes, check out the changelog and roadmap and forum posts. You'll see there's a massive amount of development going on - both adding new features and fixing bugs as they're found, and also improving already released features. I think they're doing good to build something competitive with the market leaders. They already blow MANY panels out of the water just as it is now. For modern WP hosting, it's on point.
