I do this with arch too and there's no issues. I spent 1 month without updating once because life is a bitch and it updated just fine. 1k updates sure, but meh.
I installed a KDE latex math tool that came with texlive as a dependency. Shit's awful when doing updates.
I ended up uninstalling the tool and texlive, and installed tinytex instead. I then tabood texlive and reinstalled the tool from software.opensuse.org as the YAST GUI allows you to ignore dependencies.
It works in the KDE tool and in one note taking app with latex math support, but I haven't tried adding new packages yet. I don't know how good of a solution this would be if you use latex outside of just rendering a couple of equations, but it could be worth a shot
