Has anyone actually made a legitimate alphabet key thingy?

Few languages are written in a 100% phonetic alphabet. Some are close (Serbian, Croatian), some are far (English).

I agree.

What I presented was a simple version. Wikipedia says in a few first sentences:

An alphabet is a writing system that uses a standard set of symbols, called letters, to more or less represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units.

There are actually border cases like abugida: You are not allowed to view links. Register or Login to view. 
If "perfect" alphabet is one symbol = one phoneme and syllabary is not alphabet then abugida is something in-between.

So it may be actually more like a dimension and not a binary concept.
