Does a default mysql/mariadb mapping exist?

Hi,

I am preferring mariadb over mysql, thus I do have to tell all relevant ports to depend on a given mariadb version like (make.conf):

# MYSQL/MARIADB mappings
#
# Possible values see: https://cgit.freebsd.org/ports/tree/Mk/bsd.default-versions.mk
# 8.0, 8.4, 9.1, 9.4            MSQL
# 10.6m, 10.11m, 11.4m, 11.8m   MARIADB
#
DEFAULT_VERSIONS+=  mysql=11.8m

But: Is there a way to define something like "use whatever mariadb version is considered default w.r.t the current default mysql version"?

Thanks and regards,
Michael
