I doubt it's regularmaintenance by the manual, it's most likely irregular maintenance because it's been in use for so long. I doubt that machine needs any regular maintenance apart from cleaning. Tbh if there's metal gears, they expected it to stay sealed for-life, kind of like how most manual car gearboxes have the same oil for the life of the car...
I mean, it's not bad to swap out the grease, but in most cases itwon't really make a difference if it's just a sealed metal reduction transmission.

Swapping out grease is important once mixers get old, the original grease is clay-based and it eventually separates. Oil drips out of the machine and the gear case is left with big masses of clay.
It's also not a very good idea to never change your transmission fluid

Transmission fluid is for automatics, not manual gearboxes.

There's definitely manual transmission fluid, it's much less specialized than ATF, but MTF certainly exists. Honda recommends changing it every 30-60k miles

Manual gearboxes in nearly all instances use SAE 90 api gl-5 or gl-4 oil. You don't need to ever swap it out.
ATF is something totally different.

I don't think you're going to find many supporters of sealed transmissions and lifetime fluids in the buy it for life subreddit, it's not a very long term solution, and it certainly doesn't apply to every manual transmission
And I'm specifying ATF and MTF because I'm used to Hondas, and Honda has a specific Manual Transmission Fluid. I know that it's not the same thing as ATF and that not all manufacturers have a specific manual transmission fluid

That's just how it is, my 1997 Land Cruiser had the same fluid in the gearbox until ~300000km last year when I changed it the first time, which is beyond the mileage where most cars around here get discarded.
It does not make it any worse.
Like with this grease, some guy even said it should be swapped yearly. You're not doing anything good by that - if anything you're most likely to harm something like strip threads to some panel or whatever. Gears don't require a lot of lube anyway, it's probably more important for the bearings that drive them.
These kitchen aid mixers also probably use sealed bearings in the electric motor and most people don't think about repacking those with grease.

That grease definitely is not designed to be "sealed for life", it lasts a while but you should replace it after 5 years of regular use or at worst 10 years of occasional use. I know some people who do it yearly.

And what happens if you don't?
I bet the majority of these mixers never had it replaced.

Equipment failure? I've seen a number of these with blown motors, blown gears, etc. What the hell do you think the grease is for?

I used the wrong term.
When I said "regular maintenance" I meant maintenance that should be considered "regular" or normal, after a decade or more of use... not the typical meaning of "regular maintenance" meaning frequently occurring out of necessity.
