I think this is definitely worth to think about it!
Currently (source edits form Jan 2014) LPUB does looks for the last section of the title for on certain parts "Technic Beam", "Technic Axle", "Technic Axle Flexible", some RCX cables and VEX beams, to find its annotations.
There are indeed more parts that need annotations, especially later in the instructions as well, like the Technic Panels.
Do you want to use this meta command also for instructions and propose a default handling in the meta, like axles usually display them in a circle, panels, beams in a square? May be too much and leave it up to the instruction mining program.
