OpenSUSE packages do not contain header files

mariadb.org repository configurator points to the distribution repositories (see https://downloads.mariadb.org/mariadb/repositories/#mirror=netinch&distro=openSUSE "openSUSE includes MariaDB in their repositories. To install MariaDB, simply issue the following command in a terminal: zypper install mariadb")

OpenSUSE repos does not contain -devel package. But the package "mariadb-errormessages " description is "MySQL Community Server development header files and libraries", but actually this package contains only error messages files errmsg.sys)

Probably bug should be forwarded to OpenSUSE maintainers, but would it be useful to have OpenSUSE repos also on mariadb.org with newest version and also with 10?
