99.9% of the time users want to flash "all". To achieve "don't flash
config" with current infra users would have to flash each component 
one by one and then omit the one(s) which is config (guessing which 
one that is based on the name).

Wouldn't this be quite inconvenient?

In case of MLX is PSID considered config?
