I assumed the POSIX interpretation of subshell ("A shell execution environment, distinguished from the main or current shell execution environment.") and child process ("A new process created (by fork(), posix_spawn(), or posix_spawnp()) by a given process."). But if bash systematically ties one to the other, then indeed it makes little sense to try and distinguish them there.

From the ksh93 answer, I'd say the difference between subshell and child process is merely an implementation detail, and for nearly all shells, it isn't different.
