Indeed. 'Notices' can be almost anything.

I was doing simulated flights over the continental US recently. Even small airports may have a lot of NOTAMs. Some are important (for instance, warning about objects close to some parts of the runway, or issues with a runway, or even animals or birds), but many others are completely useless.

Noise abatement restrictions ironically add a lot of NOTAM 'noise'. There should be a separate category for these, as these are not safety related.
