That's neat, I didn't know that there was much sizecoding activity with ELFs, except for the BGGP competitions [0]. (Mainly because it's not nearly as easy to output graphics than on all the old-school platforms, I'd imagine.) Does Lovebyte publish previous years' demos anywhere?
I don't know if there's a good way to search for them. Most of the Lovebyte entries can be found on pouet or demozoo.org but I don't know if there's an easy way to filter out only Linux entries.
I've written a few sizecoded raspberry pi entries, there's even a writeup of one of them in tmp.out where I loaded some code into the ELF headers https://tmpout.sh/3/08.html
Ah, then I suppose you'd be aware of my own forays into 64-bit ELFs (https://tmpout.sh/3/22.html)! I really should get around to publishing my writeup of the 73-byte minimum on Linux. (At least, it's 73 bytes for x86-64, since '\177E' at the start of the file jumps to byte 71, but it may be different under AArch64.) I have a nearly-complete draft, but I got caught on some oddities around the vDSO mapping which may or may not have changed across kernel versions, especially since the time I wrote it. Perhaps I should just jettison that section entirely and get the article out, since it's not like any of the x86 vDSOs have useful gadgets anyway.

Pouet certainly has platform filtering; try:

https://code.golf/ also has scoreboards for x86-64 Linux binaries.
