I looked at this again.
We would need to write code to find the first pitch, for the general
case like
\absolute <<{g'4 f e2} {b, c d}>>
The corresponding finding of the first pitch in \relative comes out
naturally from the code (in C, mostly) that makes each pitch reference
the previous pitch.
The meaning changes when the contents are re-ordered
\absolute <<{b, c d} {g'4 f e2}>>
and freedom to re-arrange music was a significant motivation to get away
from \relative.
Also, the first pitch of a natural segment of music is quote often at
one end of the range of that segment, so not in the most convenient
octave.
\absolute { \partial 4 g4 | c'4. b8 c'4 e'4
| d'4. c'8 d'4 e'8 d'8 | c'4. c'8 e'4 g'4 | a'2. r4 }
So I don't think we will regret passing up this behavior when the
reference pitch is omitted. Nevertheless, we could have \fixed always
use a reference pitch.

c
c'4 \fixed c { f'' g'' } c |
c4 \fixed c'' { f g } c
because optional arguments confuse simple-minded people like me, and
"\fixed c" is still easier to type than "\avsolute"
This patch leaves \absolute in place, documented automatically in
section A.19 by its doc-string.
