| Posix, the closest thing we have to a standard description of SHELL, says:
It does, but POSIX doesn't say the shell is intended to set it.
That is, it defines its purpose, but leaves unstated where it comes from.
IMO, if SHELL gets unset (it is usually initialised by login, or its
equivalent), it should simply stay unset, and not be set to anything,
until some user (or script) decides to set it again.
