Mostly that I've read the source code for an awful lot of projects over the
last thirty years and byacc use is vanishingly rare in that sample. I
think I saw it used *once*.  By comparison, while Bison use is not common
exactly it's easily in the dozens in my sample

I asked on #debian and found a way to check. It seems that you can say

address@hidden:~/WWW/writings/unfinished/lawbook$ apt-cache rdepends byacc
Reverse Depends:

So in the entire Debian package database there is exactly one byacc dependent.
Which you can see from the following I don't have installed, so it's queryiing
all packages.

address@hidden:~/WWW/writings/unfinished/lawbook$ aptitude show kimwitu
Package: kimwitu                         
Version: 4.6.1-7.2
State: not installed
Priority: optional
Section: universe/devel
Maintainer: Ubuntu Developers <address@hidden>
Architecture: amd64
Uncompressed Size: 1,163 k
Depends: libc6 (>= 2.14)
Recommends: c-compiler, kimwitu-doc
Suggests: bison | byacc | btyacc
Conflicts: kimwitu:i386
Description: Compiler development tool, complementary to lex and yacc
 Kimwitu (pronounced kee'mweetoo) is a system that supports the construction of 
 that use trees or terms as their main data structure. It is a ‘meta-tool’ in 
 development process of tools. 
 It can easily be interfaced with Yacc and Lex – the idea is that yacc and lex 
are used to
 do the parsing, and Kimwitu routines are used to built and manipulate the 
parse tree. 
 There is also Kimwitu++ (also packaged for Debian) which interfaces with C++ 
instead of C.

Note that kimwitu also works with yacc and bison.
