Many of these got added to OpenStreetMap at that time. OSMAnd will announce them, the last time (years ago) I used it while driving over some the implementation left a bit to be desired, it announced them about 10 times.

Here's a quick query visualizing just how many there are:

I think the FRA data includes information about what type of control each crossing has. It wouldn't be a huge project to highlight the less controlled crossings that are on higher speed and higher traffic routes.
