As this kind of a guitars haven`t truss rod (mostly), this is a way to straighten a neck. With time wood can become dryer and because of this process fretboard may become crooked and kinda with humps, in worst cases it can became twisted along the neck direction (that a lot more work). And even if it is a fine quality guitar, unfortunately, it still can happen.
So even if it looks like a bit "overkill" it is only way if you want some low setup without excessive buzzing.

Also we launch YT sponsorship, and already have educational content about fretworks.
Detailed description of video, tools and agents used will be a bit later on my Patreon.
