Perceived effort questions gone on watch?

You probably have it set to Workouts Only. Go the the settings for the activity and change it to Always if you want it every time.

From what I can tell it doesn't do anything to effect training status. I believe it is more of an attempt to allow journaling of training, fatigue, feeling, etc from the user perspective.... vs all the other metrics for Load, TRainingEff/Status are based on HR or Power, but doesn't take into account how fitness/fatigue is for the actual athlete.

Unfortunately most of the data is hard to pull up and/or not shown on training status or training effect pages.  However for looking back at past training and key workouts, could be helpful.  I usually just enter notes about effort, fatigue, injuries etc in the description/notes section which is very helpful when comparing different race training and recovery.  Could also be very helpful to note the Perceived Effort and Feel for people who have coaches or part of a running team.  Much easier to remember if you can just quick do a selection on the watch each time, vs going in after and filling out a description of how it went.

Kind of. Data. Hopefully in future Garmin will implement something nice with that data :) 

DC Rainmaker hinted at something similarly that NickMN says - a way to share information about the conditions during which your workouts took place with a coach or similar. Or just to remember for yourself, I guess.

"Now, I was hoping this might come through to TrainingPeaks, but alas, it doesn’t. At least – not yet anyway. This would be super helpful for coaches if it did, helping to bridge the gap between athletes that fill in complete “how the workout went” details after every workout, versus those athletes that don’t bother to do anything and let the coach try and use his or her imagination. This seems viable middle-ground."

Ah .. thanks, that makes sense, I was doing mostly workouts over the summer. I didn't realize it was specific to that and didn't know there was a setting. 

Just part of my log I suppose, a record of how I felt on that given day and how I hard I think I worked. 

Agreed.
