Could this be related to the earlier reports of excessive SSD wear on M1 Macs?
No. There is no way this has anything to do with that. That's an issue with the OS swapper algorithm, and it should be fixed in macOS 11.4 according to reports.
(Just trying to guess what they meant.)
GIFs are pretty optimized files — where each "frame" can be a diff from the previous. "De-diffing", converting palette-based pixels to full 24 or 32-bit RGB could really blow up fast.

I think the grandparent meant that if there is some leak in IOAccelerator.framework that causes excessive memory use, perhaps for some inputs this leads to swapping, leading to more SSD writes. (Just trying to guess what they meant.)

Just purchased my first Mac after using Linux for most of my adult life. How big of a concern is this? I am seeing mixed reports when looking around - should I be questioning my purchase if I was expecting my M1 Air to last a few years?
The latest information I have suggests it's fixed in macOS 11.4.

With a maximum memory size of 8G it's a bit anemic so you likely wouldn't get that much life out of it anyway, hope you got the 16G version. Apple is pretty good at the planned obsolescence game, so getting the larger memory would at least help stave that off for a bit. I'm skipping these for now, I run Linux on all my machines and it typically takes a while for the wrinkles to be ironed out, and x86 has much better…
It was still going strong after almost a decade of use and got €300 as a trade-in. If that’s Apple‘s idea of planned obsolescence, I support their plan.

As you said, mixed reports ( https://news.ycombinator.com/item?id=26244093 ) and not much followup since then. The most common worst-case numbers from that thread, if sustained, would indicate a 4-5 year maximum lifetime. If this actually turns out to be a widespread problem and Apple doesn't address it in a timely update you may see a class-action lawsuit and/or Apple warranty repair service in a few years.
Wouldn't 4 to 5 years of full-day usage be just fine for worst case life expectancy for a laptop? I've had one that gave up on 3 years, a couple months after warranty ended (that seemed to be quite common for that brand at the time).

Memory leaks don't cause swap thrashing most of the time; the leaked memory gets swapped out and then just sits there, as it is unused (hence leaked).
