In MariaDB we have a patch that allows one to use a list of keywords
for indexes and for the whole table. These keywords will be passed to
the engine so that it can take care of these that it knows about.
MariaDB is maintaining these extra keywords and will ensure that they
are kept around even if you do an ALTER TABLE back and from another
engine that doesn't support the same keywords.
This is a much better approach than having to add new code to support
any possible keyword/option that an engine may want to support.
For information of MariaDB, the community developed server based on
source code from MySQL, check out www.askmonty.org
PS: I just checked and the patch is not yet pushed. I will talk with
Sanja tomorrow and ask what the status is and when he can push
