Hi Frédéric,

This is one aspect of HTTP2 that is very likely to change.  I
encourage you to look at Roberto's work on delta-coding.

I'll note that the SPDY initial dictionary optimizes for the web as of
2011.  It is conceivable that selecting a fixed dictionary could
become suboptimal as the web evolves; similarly, it might be
suboptimal for non-web uses.
