Why bring Springer into the matter? Especially considering the well-
publicised views on LaTeX of their only net-active member of staff?

Nevertheless, it's what almost everyone does do. There are in
principle mechanisms for optical scaling type 1 multiple-master fonts,
but (apart from Adobe) I don't know many people who use them. (Though
I wouldn't be surprised if Y&Y TeX, with ATM in the background,
could do so.)

Of course PostScript is a PDL. Of course *most* use of Type 1 fonts
merely uses rescaling (with hints). It doesn't mean that it's
impossible to do better, and it doesn't mean that many people can
really tell the difference.
The real problem about (the plethora of) type 1 text fonts is that
there are but two for which publicly-available matching maths fonts
exist (i.e., Times and Lucida). Thus people who want to do
mathematical typesetting either have to go to a publisher who has a
private set (such as CUP), or to use CM, Times or Lucida.

It *is* a minor issue by comparison with the matching-fonts issue,
