This is the risk when using a limiter for the stereo main sum, instead
of using it for a dedicated channel.

There is a problem, not necessarily a serious problem in the mix, but at
least a serious problem in getting rid of a peak issue, by using the
wrong method to do it or because it's simply impossible. Instead of
pumping, I would expect distortion, if the peak needs to be limited too
much. Fortunately a little bit of overdrive alike sound sometimes is
pleasant. I know a limiter that provides special saturation settings to
halfway control the distortion.

Btw. an issue with digital recordings could be parts that were recorded
with a level > 0 dBFS, sometimes distortion caused by a limiter could
mask the ugly sound caused by a borked part that was recorded > 0 dBFS.
