A lot of devs live by the perpetual beta lifestyle, probably due to influence by lawyers from corporate-land and their day jobs. I'm checking on the mods in my modpack, and see that the 1.19.4 mod is listed as beta on Modrinth. Did you migrate to a perpetual beta lifestyle, or are they not yet ready for deployment?

0.5.2 is currently in beta because it is not finished. If you look at our last major release, 0.5.1, you will see that it is not marked as Beta, and has a full release version. 0.5.2 will have full release versions once all of the critical bugs are fixed and everything we plan on having in the version is complete.
