Are there any plans for this? I’ve got some cases where the MySQL (or rather MariaDB) query optimizer is dead wrong about his query plan, ignoring indices specifically set to speed up certain complex queries. For the time being, one would have to fall back to using this hack. It were - of course - a lot nicer to see an official way of doing this (e.g. by having a usingIndices() method in the command builder)
