Thank you for the valuable feedback! I am currently exploring how COVID-19-related updates of local businesses can be visualized / shared. I think, then crawling of data from other data sources and mapping the data to OpenStreetMap points is a better way to go. So no modification to OpenStreetMap data.

Btw, Google Map follows another approach: https://support.google.com/business/answer/9773423?hl=en

Thanks again.
