Depends... remember that even on Linux not everyone uses bash.
${foo/$bar} is a special kind of Parameter Expansion, other shells
often have someting similar.
but `cat $foo | sed -e "s/$bar//"` should work equally well, (but you
might need to massge the pattern ($bar) a bit more than we do now.

I am ambivalent. Since _I_ use bash all the time: no problem for me.
But there are a lot of systems where bash is not the system/preffered
shell.
