The other shells are also not uniform about the issue: zsh removes the
variables from the environment; bash and dash preserve them.  I would say
that keeping the variables in the environment but not allowing them to be
changed/accessed from within the shell itself corresponds better to the
POSIX's "tolerate". But I agree that it's not very fortunate formulation.
