It's a client that uses libmysqld embedded server.
Pretty much like normal mysql command line client, but it doesn't
require a running mariadb server.

I've never heard of anyone using it, I'd say, skip it.
It looks like it's just "mysql_install_db && mysqld_safe" anyway

Yes. But it seems that (at least on Gentoo) system-wide magic already
knows MyISAM files. Our magic knows Aria files. Nobody knows InnoDB.

If you'd like to use our magic file, create an MDEV and we'll update it.
If nobody's going to use it, we, probably, won't :)

They shouldn't be, but at the moment they are :(
It's https://jira.mariadb.org/browse/MDEV-10797
Subscribe to it and you'll know when they'll be free to skip.

it's an old fork of mytop, but many distributions have a separate mytop
package (I think Fedora 27 does too), so we don't ship it anymore.
