I think any real-life breakage is unlikely. GNUInstallDirs are not that
popular, and when they are used we can rather expect upstream to be
sane-ish enough not to redefine them with an incompatible meaning.

Then, even if upstream did something crazy that could be affected
by this, it's just documentation, so we shouldn't expect any major
damage.
