This is covered by the documentation:

The latest version of mod_wsgi is 2.3. Do not use 2.1 as it has some
bugs in wsgi.file_wrapper implementation.

One should avoid having instructions which refer to specific versions
of a package because people do not bother to check then what the
latest version is and so may keep using an older buggy version. That
or at least provide a good link to where they can look for the latest
version.
