First off Snap launches applications 300% to 400% slower and make a new system feel like one from 2016 because of the overhead (there are videos of launching stuff like gedit taking several seconds vs instant on arch).
Second all or I should say most of the Gnutils are being replaced by Rust varients. They are much slower and more buggy as they have not been tested than the ones written in C. Sudo is really SudoRs. My speed compliant could be outdated as this might have been fixed.
Wayland is going to be hell with nvidia users as the driver is not fully Wayland compatible yet as features are missing in display settings. The list goes on ...
I know people were rewritting Gnu utils in Rust as a cool acedemic and learning excersize but people use thse in the real world. There is no reason to change them. Especially if you do not know the algorithms of all the academic contributers. Example in Sed if you do not know how to do efficient search algorithms it will perform like crapy.
I loved Linux and Ubuntyu 20 years ago in 2005. It was the first stable distro with a great desktop. Gnome shell then Gnome 3 ruined it as it is a cell phone on a screen.
