In the next version of fontspec it will be possible to specify (or 
rather, add to) the features of the different font shapes, but for now
    \fontspec[Swashes={NoLineFinal,NoLineInitial}]{Hoefler Text Italic}
is the only way to do this.

You *will* be able to say (well, *I* can say now :) )
    \fontspec[ItalicFeatures={NoLineFinal,NoLineInitial}]{Hoefler 
Text}\itshape
when I finish up v1.6, but ironing out some other stuff is taking some 
time.

The only problem is that I haven't (been able to/worked out how/been 
bothered to) do the same thing with small caps. And even if I did, it 
gets a bit crazy. What if you want specific features for 
SmallCapsBoldItalic? I don't want to have to code in so many 
conditionals :)
