I agree that there are some things that should be already available in BP’s. Hopefully those will reduce with every update. For instance, Rama had created a Get OS Time node, which hadnt existed in blueprints and it is a very handy thing to have. Then Epic implemented a whole bunch of nodes related to OS Time with 4.5.
So, I suggested the plug-in node so that you could use it if it was an urgent need. Otherwise, this would get better attention in the forums as a feedback.
