I wouldn't call it confusion, at least not on the part of the Unicode
Consortium. There is an old tradition of using a dot below to indicate
vocalisation. I know I encountered it (and in the context of Sanskrit and
Proto-Indo-European) before I encountered the IPA symbol ring below. The
1969 edition of the Oxford Dictionary of English Etymology uses dot below
for both Sanskrit and PIE. Indeed I recall reading of some dismay at ISO
15919 because fonts with r with dot below (with and without macron) had to
be supplemented with r with ring below (with and without macron).
Underdotted l is also used to transcribe the Vedic/Pali consonant
corresponding to retroflex da - isn't the Vedic/Pali consonant plain U+0933?
