Well I am far from agreeing about some of Gnome's technical choices but I am posting under the end user position. And I must say that as an end user, the client-side vs server-side decorations hasn't seemed to affect me. On modern apps I am looking for a burger/3 dots icon for settings, on more legacy one a file->preferences of file->settings and that's it.
Even if Gnome/GTK-4 supported server side decorations the problem of the heterogeneous app ecosystem would not be solved and you can observe the same regardless of the DE or even OS.
As a user the only major complaint I would have about Gnome is the regular breakage of extensions. On most distros it isn't an issue but it makes it rather unsuited to rolling release distros unless user is willing to regularly play with his package management config to prevent updates. On my Fedora machines it is not a big deal as the gnome major version is only upgraded on major Fedora version so I usually test with a VM before hand and if there is an extensions I really want to have I'll fix it o just wait a few weeks or months for the extension to be updated (or a fork being made).
