I agree on the tmpfs guess. However, when not using a helper, users
might anyway tend to do the manual build process in tmpfs. OTOH I
sometimes still use a discontinued helper. For small software I just run
the helper and for large software I run an alias [1], to build outside

When using the manual build process, then depending on the size of the
software to build, I also chose between tmpfs and no tmpfs for the build

The usage of tmpfs isn't necessarily related to the tools somebody does
use to build packages ;).

$ grep naourt .bashrc 
alias naourt='echo "Not AnOther User Repository Tool";rm -rf /{.,}tmp/yaourt-tmp-$(id -un);yaourt --tmp /.tmp'
