Actually, in most cases, the default line height is perfectly fine with me. I mostly use Fontin as my body font and I like it with no set line-height. So yes, I do want a line-height less then 120%. If I am dealing with an ePub where the publisher has embedded the font Charis, I want a line-height of 110%. So again, 120% is too large for me.
Can this line-height diddling please be turned off by default until specifically called for?
