It was from many years ago when people dropped custom charsets (VNI,
TCVN...) in favor of unicode. There were two groups: one favors
precomposed form, the other prefers composed form. There was no
standardization so people just used what they liked. All people is
using precomposed form now, I believe.

It maps alphanumeric letters to precomposed form letters. But I don't
think this layout really matters in real life. Vietnamese input
methods have a long traddition of using theirs own way: US layout, no
dead key, no preediting window, usually emiting backspace to modify
some letters. These input methods operate on "word" level instead of
letter level, which resembles how Vietnamese text is written.
