i did a quick test, how good 'brotli' performs in compression
on binary files versus e.g. xz/lzma...here it is:

bytes:
10.905.600  uncompressed
 4.192.280  gzip -9
 3.362.626  brotli -11
 3.098.216  xz -9 --extreme
 3.097.691  lzma -9 --extreme

the uncompressed file is an unsquashfs'ed rootfs from
bin/ar71xx/openwrt-ar71xx-generic-root.squashfs and then
tar'ed.

so nothing to talk about for now, especially the
decompressor is HUGE and this must be taken into account.

bye, bastian
