Realized after sending I may not have been as clear as I should have been.

AddEncoding inserts a Content-Encoding header that specifies that the file is
gziped without changing the content of the body. The Subversion client
decompresses the file but then realizes that it doesn't match the checksum it
expected and issues an error.

The purpose of the configuration option is to store pre-compressed files on
disk that are served to clients that can support gzip Content-Encoding without
needing to do the compression in real time while the client decompresses the
content on its end and uses it seamlessly.
