If you are using effects as part of sound design (i.e. reverb or slapback to get a certain guitar tone, or any type of effect for a synth) they should be printed to the track.  But record it into the track and commit to it.  Most of the time if I see FX tracks delivered as part of the stems, I discard them, unless there is a good reason to keep them.

I used to do this, however I found that quite often the sound that sounded perfect in isolation did not fit in the mix well... and because it was already effected, it was more difficult to work with and get it to fit/
 
What I do now is clone the track and the FX and use the original track + FX as a reference, but use only the cloned track in the mix, where I can tweak the FX to make it fit better.
 
Beyond the obvious like EQ, things like delay volume, reverb time etc can drastically alter how a track is perceived in the mix. Soloing the cloned track would sound thin and lifeless, but in the mix it would sound just like the original.
