That's a privilege of big countries like Germany, although Kazakhstan might qualify as well. I live in Estonia, a country of 1.3 million, and although there is a standard Estonian keyboard layout, there's basically zero products using it. [1] The local stores primarily sell laptops and desktop keyboards with the US ANSI layout. This is especially annoying, because ISO layouts like Swedish, UK, or even German would be a closer match to the Estonian standard. I also fear that this is impacting how many young people get into programming, because the Estonian layout binds three essential programming characters < > | to a key which physically doesn't exist on the US ANSI keyboard. I've seen it in practice how a friend tried to learn programming with his US ANSI keyboard, by copy-pasting those characters when needed. Not exactly an optimal situation. [2]

[1] Most keyboards had the Estonian layout in early 2000s, but they soon rapidly lost market share, mostly due to laptops if I had to guess why.
[2] Why not use US ANSI layout in the OS to match the keyboard? Because it doesn't contain characters required to type Estonian words.
