Haha! This is DWARF FORTRESS. A lot of people would say that things like soap, beekeeping, thread-making, and the like are "not important enough to put in." That is not the vision of the ToadyOne. Complexity=FUN. Ergo, why not add something like snack cakes? It's an extra bit of flavour that will be pretty much unique to Spearbreakers.
Soap is incredibly important. It keeps dwarves happy, keeps them clean (absolute necessity if you find a syndrome-bearing forgotten beast), and keeps your best soldiers from getting fatal infections. Just being clean lowers the chance.
Beekeeping is important, though not necessary. I don't know if you've ever brewed mead (probably not), but that stuff is cheap, overabundant, easy to make, and dwarves love it. Sells for a pretty good amount, too, and has the side effect of producing food for the fortress. Not drinking the same old booze lately will also help with tantrum spirals, and going aboveground helps with cave adaptation.
Thread-making is absolutely essential on all counts. Ever tried to suture a wound? Can't do it without thread. If you don't have thread, you can't make new clothes for your dwarves, either, which means they'll start to go around naked at year 5 or so, and that means a definite, unavoidable tantrum spiral.
Snack cakes are just flavor (no pun intended), and pointless, random, unheralded flavor at that. They don't fit in with the grimdark setting of Spearbreakers
at all. Not to mention, they don't fit in with Dwarf Fortress in general. It's like lollipops or candy canes. Maybe jell-o.
edit: If you've read the thread, you'll know that for us, plot and setting are Serious Business. There was a huge argument over a shadow creature because it was from a different series, something got written as non-canon simply because it was overpowered, and several stories almost got completely rewritten just because it was considered presumptuous for a character to be quite as important as they were made out to be.
Lolfail and his array of characters are fine mainly because he doesn't try to force his creations onto us, because his characters don't actually seem to be all-powerful or Mary Sue-ish (from what I've read), and because he mostly keeps his stuff as sidestories, without trying to control everything and everyone. (Plus, I don't really understand his character all that well - it's a bit confusing.)
