Some tests are skipped by checks in suite.pm. It is redundant to
have an sql-level run-time check in the .inc file itself.

In some cases it's not only redundant, but dangerous.
After one bug in 10.2 innodb.create_isl_with_direct failed
to start InnoDB, but the server started fine (just without InnoDB)
and instead of failing, the test was skipped by run-time check in
have_innodb.inc.
