I sure we document that variables in PKGBUILDs should start with an
underscore...  and we do!

man PKGBUILD:

If you need to create any custom variables for use in your build
process, it is recommended to prefix their name with an _ (underscore).
This will prevent any possible name clashes with internal makepkg
variables. For example, to store the base kernel version in a variable,
use something similar to $_basekernver.
