Actually, glowpoints have a lot of unexplored potential (they should have been used for manouveing thrusters and even contrails, if the latter were not a retail feature).
Glowpoints can be placed on a model very precisely, much easier than manouvering thrusters. Numerous types allow for wide range of options, while "proporties" field allows for defeining everything that can't be done using radius and normal. Table defined coordinates make creating a "helper" in PCS2 and moving it around the model to get the exact coordinates nessesary, which isn't very comfortable.
Also, since it's now possible to rescale models in PCS2, adapting table defined stuff such as manouvering thrusters and trails for a rescaled model either requires you to recalculate them in an external program or use a "helper" to place them at the correct locations. PCS2 moves glowpoints automatically while rescaling the mesh, saving a lot of time and effort.
I think that some day, manouvering thrusters and trails should get an alternate method of defining them which would allow them to use glowpoints of yet another type instead of just table entries.
