Why/how does the MariaDB client depend on libdbd-mysql-perl?


I am returning to this age-old discussion about libdbd-mysql-perl as
dependency in Debian:

In MySQL 5.6 this dependency also still exists:

Package: mysql-client-5.6
Architecture: any
Depends: debianutils (>=1.6),
         libdbd-mysql-perl (>= 1.2202),

But it has been dropped in MySQL 5.7 packaging. In 5.7 it is not even
a Recommends or Suggests, but completely removed.

I don't know what to do about this because I don't really understand
what or how the mysql client does with perl library dependencies. It
is a C program, does it really use the perl library in any way? So
auxilary script does something?

Can we drop the dependency on libdbd-mysql-perl, and starting from what version?
