Cursors: Is superimposing the same glyph a feature?

I am working on feature requests 22873 (multiple fake cursors) and 17684 
(visible crosshairs that track the cursor position, and a visible fill column 

When draw_phys_cursor_glyph (w, glyph_row, DRAW_CURSOR) happens, the background 
of a glyph is _not_ filled (i.e, !s->background_filled_p).  This is presumably 
for a situation such as a FILLED_BOX_CURSOR so as not to erase the colored 
rectangle around the glyph.

In the case of an HBAR_CURSOR; however, the result is a second imprint of the 
same glyph -- creating a bold appearance of the glyph with the cursor.  Is the 
bold appearance "a feature", or is this something that has just been overlooked?
