It is just defensive programming.
If it is off by default, you're less likely to break builds.
E.g. builds on exotic platforms that are not tested regularly.

After a while, the defaults should be switched. E.g. it is now
time to make cylinder and opcode support default, and force the
use of --without-opcode and --without-cylinder if you do not want them.

Lastly, it pays to be paranoid sometimes: if there are reports of
crashes after e.g. cones were introduced, you can always test
causality by removing the feature at configure time.
