Dear gang,
For \addfeature and the like, a virtual font feature defined in terms of a CLD local function behaves differently from other font features. MWE:
==============
\startluacode
local function squeeze(tfmdata)
     for k, v in next, tfmdata.characters do
         v.width = 1.75 * (v.height or 0)
         v.depth  = 1.75 * (v.depth  or 0)
     end
end
local specification = {
     name        = "sqtfm",
     description = "test",
     manipulators = {
         base = squeeze,
         node = squeeze,
     }
}
because much more has to be done to satisfy the backend (liek advance 
with and such) .. you cannot just change dimensions on the fly for 
characters that could potentially be shared just as you can't change 
glyph dimension mid document
