Well I'm not sure really. My point is the latin scripts seem to be a mix of both. It is only when gothic and roman scripts differentiated we saw a clear division. So the point im correcting on is that it isnt latin based scripts that use the capital A form but rather the Roman basesd scripts.
I just cant speak for what languages use gothic scripts, you might be right there and its limited to germanic countries.
I did not follow your entire conversation, but please have three German cursives
(1) Kurrent (variants from 1500-1900)
(2) Sütterlin (taught in schools 1915-1941)
(3) Vereinfachte Ausgangsschrift (1969 developed, taught since then in some states)
Notice how the A changes to match the Latin.
