Same here. Storage is not that expensive so I do NOT care to squize every byte out of archive. Also, im more into retro, so portability and memory usage is more importand for me :)
Regarding your first remark: high ratio data compression has its time and place, and I personally understand that to many people it is not very desirable. In a lot of scenarios something as plain and simple as LZ4 generally suffices.
On the other hand, there is an unofficial (= unsupported) port of bzip3 to older (386+) machines that run MS-DOS6.22. I have prepared it for a retrocomputing meeting in Ontario that I attended a while back. Let me know what you think :).
