The MDEV-19780 has the reason. Quoting:


  TokuDB is deprecated in the 8.0 series and will be supported through
  the 8.0 series until further notice. This storage engine will not be
  included in the next major release of Percona Server for MySQL. We
  recommend MyRocks as a long-term migration path.

Percona is the owner and the maintainer of TokuDB. We package it, we fix
MariaDB-specific bugs, but most TokuDB bugs are reported to and fixed by
upstream. When Percona deprecates TokuDB, we don't have much of a
choice, but to do the same.
