I agree. From XBD 8.1 "Environment variables":
Environment variable names used by the utilities in the Shell
and Utilities volume of POSIX.1-2008 consist solely of
uppercase letters, digits, and the <underscore> ('_') from the
characters defined in Table 6-1 and do not begin with a digit.
Other characters may be permitted by an implementation;
applications shall tolerate the presence of such names.
This means bogus-variable should not be used by sh -c 'export -p' (and
as you mentioned, output from 'export -p' needs to be suitable input
for the shell).
Thanks for reporting, and sorry for a slow response.
Hope that helps,
Jonathan
