That is exactly why I use the psnfss fonts. They are stable, the
spacing doesn't change.

Yes, but what was the conclusion? As far as I can see the metrics
only changed in terms of the character bounding box. But these are
not considered for the advance width. So the change in metrics is
irrelevant for typesetting with TeX.

Yes, but what is the problem? We are not talking about "other fonts",
just the ones preinstalled by psnfss. We know ervery bit of those
fonts, so no need to reflect the spacing etc. in the filename, since
e.g. phvr8t will always have the same characteristics thougout all

Right, but qx isn't supplied by psnfss anyway, is it? So you'd have
to make your own font; but I still can't see the drawback in using
those fonts for 99% of [texts covered by ec encoding]. I can agree on
"don't mix fontinst installed fonts with afm2... installed fonts when
you need same em width (and alike)." But for most texts I bet that
this is not an issue.

Absolutely. The choose the adobe metrics from psnfss, but as I am
told the URW metrics have somewhat questionable kerning data. And
using URW metrics with Adobe fonts will break on glyphs that are in
URW but not Adobe.

I should make a macro in my Mailreader for default answer for those
questions and put it on a easy to remember key :-)

That is really good. Let me see what I can do with respect to
