It's were the feature really shines. The timestamps eases comparing
output from show commands across multiple devices (in separate
terminals), especially tomorrow. And you never remember to turn it on
until it's too late if it's default off...

BTW, terminal timestamps are enabled by default on IOS-XR since 3.8,
so this change has already happened.
