Update multi-select lookup via API? Or allow for import of multi-select Lookups?

When will the ability to update a multi-select lookup via API be available?
Also when will we be able to import a record with multi-select lookups?

I understand a linking module can help with this, but linking modules in our scenario would only be used for backend/operational reasons and we don't want to clog up our crm with modules that our team has access to but that they don't personally use, if that makes sense.
