I'd tend to agree with that for scripts that get installed - it would be 
good for them to work on systems without bash - but for the build and test 
process I think it's reasonable to use bash (just like various other GNU 
tools are needed).

However, the installed scripts certainly aren't purely POSIX at present; 
various do at least explicitly use bash in their #! lines.  Many use $"" 
for i18n, as an example of a bash feature being used.
