Review comment:
As an arbitrary threshold this isn't a terrible choice. Did some
research. [Antirez's smaz library readme](https://github.com/antirez/smaz) has
this comment: _To compare this with other libraries, think that like zlib will
usually not be able to compress text shorter than 100 bytes._ It's just one
data point but someone who put thought into this space came to that conclusion,
it's acceptable as a starting point.
