Synthesized stuff (or transformations) are not the same as designed
condensed or extended fonts. I would ask two things:

- that you do not *encourage* agents to synthesize font-stretch ("allow" is
okay I guess, though you should understand the results will always be crap)

- that for any agent that does do synthetic stretch, it is OFF by default
and turned on by some additional flag or option.
