There were and have been over the years several hefty boxes with ALL of Bach (Hänssler https://haensslerprofil.de/shop/werkausgaben-boxen/die-kompletten-werke , really good recordings, I do have some but by no means all or most of them) and all of Beethoven, and all of this or that.
“ALL” is of course debatable, as there may always be some odds and ends to include or not include, what is “ALL” anyway, all Bruckner Symphonies or all VERSIONS of ALL Bruckner Symphonies. (I have a set that is literally the latter:
).

I can’t say that these box set’s take the fun out of it, quite the contrary, they really allow to have a good overview dive into a composer. I don’t have a lot of “composer complete” boxes, as they used to be expensive (not anymore, you can get the Hänssler Bach edition now for a fraction of what it originally cost), and seemed a bit “overwhelming”, I preferred to spread out my funds for music over various different music and couldn’t just dump it all on ONE composer (and therefore not buying a lot of other music, like film music).

I do have some “specific” box sets, like all of Mozart’s symphonies, or Piano concertos, or all of piano sonatas.
