My opinion is that unlike Consonants, the Vowel_Independent are generally
not needing an extra Dependant_Vowel to alter them (only vowel modifiers
for tone, stress, nasalisation, or newer distinguished phonetic variants
needed to represent words borrowed from other languages...), and also
generally don't need a Virama-like character to remove their inherent vowel
sign. These Vowel_Independent also generally don't take the additional
diacritics used to modofy Consonants.
So the Vowel_Independent can be viewed as if they were already precombining
the same "null" Consonant (not encoded, though some phonologies may render
it with a true plain phonetic consonnant like a glottal stop, later added
to the abugida as a true Consonant with its own inherent vowel; something
also occuring in Semitic adjads) with their associated Dependant_Vowel.
Now if you analyze the existing independant vowel A, it is by itself the
representation of this null consonnant associated with the inherent vowel.
That vowel A followed by a virama then makes sense to represent a non-null
consonnant like the glotal stop. This independant vowel A is different from
other independant vowels, and is more like other consonnants (this can be
said too about the Semetic Alef perceived as this null consonnant with its
inherent vowel dropped). This is the only case where the distinction
between indepedant vowel and consonnant is really fuzzy (unless we analyze
it like the vowel A in western alphabets).
And there are some transforms (or orthographic evolutions) where pairs of
combining Dependant_Vowels could become a single Dependant_Vowel followed
by a Vowel_Independent (or could also evolve to an abjad or a plain
alphabet like Hangul), which affect things like collation and transcription.
In the history of scripts, the separation line may become dofficult to draw
when abugidas, alphabets are evolutions (in opposite directions) of Semitic
abjads which initially did not separate phonemes but only syllables (like
today's syllabaries, largely kept in sinograms and even graphically in the
Hangul alphabet). It is with western alphabets that the syllabic
separations have become almost invisible (so much that hyphenation rules in
Western alphabets have become difficult and they incorporated spaces and
punctuation to separate words, but their origin comes in fact from Semitc
abjads at a time where vowels where not written and had to be guessed)
