Exactly!
One of the big challenges for "beginners to photography who want to go deeper" is that modern cameras contain such sophisticated exposure metering algorithms that it's very hard to understand why the camera's multi-segment/evaluative meter picked the exposure it picked. Moreover, for many photographers and many shooting scenarios, those automagical exposure settings are good enough. However, sometimes the algorithms fail because of the shooting conditions and sometimes the photographer wants something different from the standard look of standard exposure settings.
In contrast, spot metering uses no inscrutable algorithms, has easily explicable effects on the image, lets the photographer really understand tonality because that is exactly what the meter measures, and gives the photographer total control.
In that regard, spot metering is a great idea for beginners who want to understand the relationship between tonality and exposure.
