Default shell for the manitcore user in RPM

Can anyone say why when creating the new manticore user when installing from RPM, the default shell for it was set to /bin/bash instead of /sbin/nologin or /bin/false?

From manticoresearch/dist/rpm/
useradd -M -r -d /var/lib/sphinx -s /bin/bash -c "Manticore server" -g %{manticore_group} %{manticore_user} 2>/dev/null || true

It should be /bin/false. Seems we overlooked this 3 years ago when we create the spec for rpm.
Will be fixed.
