I am reviewing some of the Transformers I either rarely use or have never used and came across the Feature Holder. 

Can someone provide me an example or two of why/when it would be a good idea to use the Feature Holder Transformer?

Lots of scenarios! One I used recently was when I needed to make subsequent calls to two apis. I wanted all features to call the first API and get the respone before calling the second. So a FeatureHolder was used between the two HTTPCallers to ensure that happened

I recently wrote a blog post about a scenario in which I use the FeatureHolder before writing data to an Enterprise Geodatabase.  Link below.
