"Environment variable names used by the utilities in the Shell and
Utilities volume of POSIX.1-2017 consist solely of uppercase letters,
digits, and the <underscore> ( '_' ) from the characters defined in
Portable Character Set and do not begin with a digit. Other characters may
be permitted by an implementation; applications shall tolerate the presence
of such names. "

Bash tolerates those names by passing them through to children in their
environment and not attempting to create shell variables from them.
