This isn't a resource problem, it's a code problem. The IETF wants 10-15
year old hosts to be able to connect to a network and perform basic

be there. New functionality can optimize for different factors, but
making older host stop working is frowned upon.
Fortunately this is a solved problem in capacity planning: you replace
machines often enough that they're not constantly out of service being
repaired. 10 to 15 human-years is the equivalent of 70 to 105 of the
dog-years we use in this silly business (;-))
I have quite a number of consumer devices from 2000 or earlier still
running, consumer endpoints (aka IoT devices) do not get updated very much,
if at all.

Interesting thought: I wasn't expecting consumer devices from 14 years ago!
What do you have?
I've got 4 Tivo's that have been in operation since 2000, they have add-on
netork cards instead of the original dial-up.
At the Scale conference earlier this month, I used a couple of dozen wndr3800
APs that were sold in 2010. They are actually still used extensively (I have
updated software on them). I've seen a lot of people who still use the stock
AP/router their ISP gave them when they signed up for service many years ago.
Technology refreshes happen at (some) companies, many homes tend to run things
untilthey break.
Even at some companies, I've seen them running 7+ year old hardware in
mission-critical production situations.

In our house,
* the cable modem is about a year old,
* it's predecessor was about 5 when it died,
* the old printer was 3 years old
* the new one is about 4
* my homemade PVR is about 6, and is starting to look elderly, and
* the old cable box was about 3,
* the new one about one
* and my netbook is older than the PVR by maybe a year or so (;-))

(I intentionally skipped IOT devices, as I expect they could change/pivot
hugely about the time the market starts to mature,
