It would be nice, but unfortunately there is a historically imposed inconsistency which usually noone notices, but which gets obvious when displaying vertical lines in the depot gui or simliar. [0]
The original vehicles have a length of 28 pixels in the depot view, while a lot of NewGRFs use 32 pixels. OTTD currently evaluates this flag on a per-vehicle basis, so trains with the same length in tiles can occupy different space in the depot gui, depending on whether they use 28px or 32px vehicles.
When you add a grid to the depot GUI, you cannot hide this inconsistency via obfuscation. I.e. you would need to add 4px gaps between original vehicles if there is only one 32px vehicle. (which is what TTDP does afaik).
[0] Similar issue as with catchment areas. They are inconsistent for acceptance and supply, which is preventing a show-catchment-area for already build stations for years. (Though since there are no NewGRFs involved, this could actually be made consistent via some advanced setting.)
