Yes mama. Its a pretty big part of Telugu culture so my grandmother did it every year my mother sometimes. I understand though that its not popular in Kerala so I'm not surprised about Mrs K not doing.
hate to disappoint you amala, but i have a suspicion, mrs K borders on agnosticism.
her mother aka ma-in-law once whispered to me, that mrs K does not like all this god stuff
i have lived with it for 31 years. i think she enjoys the social part of pondugal iduthal (as we call sumangali prarthanai)
good lady she is
