Your pronunciation is the oldest one which is still pronunce in Aamdo side in Tibet and as well in Ladakh but it doesn't mean that all must pronounce same as you pronunce.
If the productions of both ལྐ and ཀ are same then what is the uses of this latak etc. We are learning them for torturing outself 😄 In my language ལྐ་ not ka it is Lka not ka ལྒ is Lga no ga others are also pronuncing in same manner..
