How about this idea: At Emacs build time, we check whether Bash is 4.4

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.
The first part will only work if Emacs is used on the same system
where it is built, right

No, it merely assumes that the build Bash version is not greater than the production Bash version. Although this is the typical situation, you're correct that it might not be true in general; if that's a problem (which I doubt), we can easily provide a configure-time option to override the default assumption.
