If a maintainer wishes to have a USE flag to link to libmariadb, that's up to them. Use of mariadb-connector-c may need patching (for mariadb_config or mariadb.pc) or build options to look at the other library. This may be beneficial for licensing purposes (GPL-2 vs LGPL-2.1) If such a flag is popular enough, then a global description can be agreed upon. Brian
