Depend on location probably. Smaller town or side road small stall usually have more traditional offering. Most of the larger shop have to cater to all and youngsters choice nowadays.
But yeah, a lot of malay foodstall is basically goreng goreng, western, yong tau foo. The one that serve traditional dishes are usually the economy rice. It still out there for sure but it's getting rarer i think.
I also wonder about our fellow Malay diet nowadays. How much has changed as we transition to modern lifestyle, and how much they keep to their traditional recipes?
