Unofficial Skyrim Legendary Edition Patch

Trainers that can be followers do not receive gold after training a skill with them.
It seems that this was a bug fix on a exploit in Skyrim.

Feandal of Riverwood can be taken as an example.

Clarification as to why I think this is an issue:
To my experience, items that are given to NPC's (excluding quest items) are stored in the NPC's inventory after the trade (excluding vendors).
Also, other trainers that aren't followers do receive the gold you give them for their service (training).

This makes it inconsistent and therefore I presume a compensation is needed.

Suggestion on actions to change this fix (implemented in 1.26 of USKP):
Alter the script of followers on the location where the follower opens up his/her inventory then include the following check;

<pre class="_prettyXprint _lang-nocode">
-- Your code
if NPC.CanTrain then
Remove gold from NPC's inventory

-- Old code
Show NPC's invetory
</pre>

I hope I've made my suggestion clear and look forward on reading your response.
