For example, my students regularly use Emacs on a server running RHEL 7, which ships Bash 4.2.46, and as I understand it, this is the most recent RHEL available. How about this idea: At Emacs build time, we check whether Bash is 4.4 or later, and if so we use a term.el that assumes bash 4.4 or later. Otherwise, we use a term.el that interrogates the shell dynamically for whether it is shell and if so what its version number is, the first time that Emacs runs a process under a shell.
