  The documentation claims that SLF4-2 is binary compatible to slf4j-1, from a client perspective:
   * https://www.slf4j.org/faq.html#compatibility
   * https://www.slf4j.org/faq.html#changesInVersion200

  But for example LoggingEvent.getMarker() in slf4j1.7
was changed to LoggingEvent.getMarkers() in slf4j-2 and now returns a List of Markers instead of a single Marker.

This looks like a binary incompatible change to me. Would it be possible to restore the old getMarker() method as deprecated, in order to restore the binary compatibility?

 If you are interested, to avoid such changes in the future the  bnd-baseline-maven-plugin could help to avoid such change. 
 But I would have to find out first, if it is possible to perform the check like if the major version was not increment and thus removals are forbidden.  Maybe this will also find other binary incompatible changes.
