There must be some kind of universal law that states that projects
(I'm not even talking 'bout compressors) that have >N% "attention
market share" get even more attention no matter how 'bad' they are,
and that projects having less than those N% get no attention at all
because everybody claims "no one uses it so what". That way, projects
that are just recently nascent can hardly take off no matter how
'good' they may be.

These belong to the set of tools that faded away. LZH and ARJ were
absolutely normal in the 90s and not having an uncompressor for them
on your DOS system meant you suck, because, (at least ARJ) did often
provide better compression than PKZIP. As time passed, tools with
other distinct features arose, such as (as CRC was already there)
archive repair metadata, or even higher compression ratios.
