Following a discussion with Paul Isambert, I asked Hans today about 
microtypography, and he released a new ConTeXt beta containing the 
necessary code for slanting, extending (we already had these), expansion 
and protrusion; and Khaled merged it in the git repository (see 
This is a great milestone and I'm sure it will make more users use 
luaotfload, as XeTeX does not support microtypography.

Next job is to integrate it into fontspec, with a warning when activated 
under XeTeX?

The question I wanted to ask is whether we should enable it by default 
in luaotfload or not... Not so many people know what protrusion means, 
but if they knew I'm sure 99% of them would want it, so it seems logical 
for me to enable this kind of features by default, with of course 
options to unactivate it. I don't really see any disadvantage, except a 
different rendering between XeTeX and LuaTeX, which is not really a 
disadvantage for me... What do you think?

Thank you,
