Yes, but emacs should allow a number of possibilities rather than being 
prescriptive on its use.  For instance, it does not allow multiple tabs at 
start of line, which happens with legacy codes (e.g. in fortran).

I suggest a rethinking and the introduction of a set of function that help the 
setting up of space and tab functionality.

whitespace-mode should also be extended to allow users to set colour hex codes 
for the various highlighting regions.  For instance, whilst the highlighting of 
trailing spaces in vibrant, the one used for tabs suffers from a very low 
contrast ratio.

Efforts should be directed towards applying accessibility measures for which 
there are actual standards (e.g. WCAG).  One can also use
a colour wheel with equally seperated colours in terms of contrast ratio for 
increased vibrancy, which is another good measure.
