Suppose you have a type1 font that offers all the glyphs you need.
What is the (efficiency) advantage to making a composite virtual font,
rather than simply using what you've got? In my experience (almost
exclusively typesetting Latin-script text) the automatically-generated
8r encoding of type1 gives me all I need.
In such a case, it's a ludicrous *waste* of effort to create a new
virtual font: unless you're wandering into typesetting of languages
that aren't covered by 8r, to do such a thing would be ridiculously

Sebastian was answering a different question. You were talking (in a
separate branch of the thread) about the awfulness of typesetting
using linearly-scaled type1 fonts, and Sebastian retorted that if it's
what the designer specifies, it's what he'll do.
Michael Downes remarked that linear scaling is bad when the sizes get
really small, which only really happens in maths; you then responded
that we need a "bit of work" to add meta-ness to the existing fonts,
and I responded to suggest that the "bit" was more likely to involve
armies of designers and metafont hackers.

I.e., you actually _knew_ all the above...
