In theory offering more than just one is "trivial" in the sense that for OS/1337 the idea is to have statical binaries (and maybe the few necessary configs) as "#packages" so it's just a download as an archive (#bzip2 because it's available in #toybox) and just pull that and place them in the system.
OFC absolute hardcore folks will literally do #eMail just with #curl, #cat, #sed & #awk I guess, but ideally offering a convenient alternative like #neomutt is better.
