try to make them less confusing for users.
Hopefully, if the version string will be changed like

- mariadb Ver 15.1 Distrib 10.11.2-MariaDB for Linux (x86_64)
+ mariadb from 10.11.2-MariaDB, client 15.1 for Linux (x86_64)

users will be less inclined to reply "15.1" to the question
"what mariadb version are you using?"
