When electronic switching came along in the early 1980s, some small
towns then lost their ability to dial only five digits for local
calls. Earlier in this newsgroup Neal gave an excellent explanation
of absorbers.

Fast forward to today, it seems most callers have cell phones which
require ten digit dialing and also have speed call, so the ten digit
dialing is not a burden.
I still have a rotary phone and the ten digits are a pain. But I
mostly use a Touch Tone phone for outgoing calls.
Indeed, I wonder, today how many rotary-pulse calls are offered to
telephone exchanges. I also wonder how long they'll be accepted.

I'd guess "forever" - the switch vendors have already sunk all the
costs for development and marketing, so they'll be very reluctant to
remove features that are still in use and for which they collect
royalties every year.
In addition, I doubt ANY politician would allow any change that might
cause some voter to be cut off form 911 or their doctor. All things
considered, I believe that the "500" set will be usable for the
foreseeable future.

UPS assemblies come in a huge range of capabilities, and that includes
the run time supported by the batteries used. I worked on one at the
US Government Printing Office (GPO): it was a conversion of the
gigantic wet cells in the basement from supplying nothing but
emergency lighting to supplying a huge UPS system that would keep the
printing presses' controllers from forgetting what they were doing
when power was lost. That would prevent very large amounts of waste
caused by starting large print jobs over from scratch.
I also worked on a UPS system that included a 20 foot diameter
flywheel and a forward only clutch. The electric motor which turned
that flywheel was a genuine monster. The 2 parallel back up
generators were designed to come up to full operating voltage and
current in 2 minutes. At full designed load that flywheel would not
let the power fall more than 0.50 Hertz out from 60.0 Hertz for 5
minutes. We often joked that if anything ever happened to that set of
bearings that people 25 miles away might be crushed. When you are
supplying computer arrays which bill communications satellite usage
time you do not allow the power to falter. Now that was a UPS!

I was at the California PUC meeting to discuss the 415-650 split (many
years ago). Stanford University pointed out that their catalogs were
in high school libraries around the country, and were often not
refreshed for many years. At least one security contractor said that
he would have to go out to every single property (and he had thousands)
and re-program every dial-out device. PUC did the split anyway,
promising us at least ten years of stability (big deal!).
Two years later, they were back to request another split. I went to
that meeting, and after hearing their arguments, I told them that even
though the many competing phone companies did not want to tell the
public how many lines they needed, the PUC had a right to that
information, and all those companies who needed less than ten lines in
an office could split a single block of 10,000 lines rather than giving
them 10,000 lines each. They cancelled the split, and we have not heard
anything about another split or overlay for 650 since.
