Has the ability to add custom (i.e match the shape of the space floor surface ) illuminance map shapes in OpenStudio been implemented?

The answer to this question suggests that this was going to be delivered in OS1.9

Nope. Unfortunately, there really hasn't been funding for Radiance-related work in OpenStudio in a couple of years, save for bug fixes and package (installer) maintenance.

It's trivial to add illuminance maps to an OpenStudio model programmatically. Difficulty is introduced when you wish to make them non-rectangular. More difficulty is introduced when you wish to make use of these maps beyond EnergyPlus. The main intent of the illuminance map object in OS is to mimic the same object in EP, which can only be rectangular. Radiance has no such limitation, but again the OS illuminance map object is tied to EP compatibility and so is defined by an origin, length, and width.

Arbitrarily-shaped illuminance maps would be best handled outside of the OS model, directly generated off of the exported Radiance geometry or something like that.

Could comment on how difficult this would be? And perhaps the key steps in the code/measure that would be required?
