The iPod Classic is a current model (depending on how you count them,
about the seventh generation of the original model).
The more miniaturised/compact the device, the harder it is to replace
the battery. People buying them seem to like small devices and don't
seem to care about being unable to replace the battery themselves.
I'm sure Apple service agents can replace the battery, but it is likely
to cost enough for the lower end models that it is not worth it. I doubt
they even bother for the iPod Shuffle.

I have a three and a bit year old iPhone which still works fine on its
original battery (it is starting to feel like it is a little shorter
than when it was new), and an eight year old iPod which doesn't last
long on its original battery (but these days I only use it plugged into
the car so I haven't bothered to replace the battery).

According to their web site, Apple is currently rating iPod and iPhone
batteries at 400 charge cycles before they drop to 80% of their original
capacity (don't know offhand if that was true historically or just for
recent models).
If you used the iPod or iPhone's full battery capacity and recharged it
every day, the battery life would be somewhat reduced in the second
year, but if you only used part of the battery capacity each day it
would last longer before reaching that point.
They don't specify what happens after that, but I expect the operating
time would continue to decline. Five years of heavy use on the original
battery isn't likely, but five years of light use (or mixed
powered/battery use) is quite possible.
The iPad and integrated batteries in recent Mac notebooks are rated for
1000 charge cycles before reaching the 80% point, so they should last
three years even with a full daily discharge/recharge cycle, and longer
than five years with moderate use on battery.
Lithium-ion batteries have aging effects as well, so even with light use
they would be showing signs of reduced life after five years.
