The wear and tear it saves on your compressor not having a tank is not insignificant and a good reason to dump the tank. This doesn't matter with a belt driven but is a big deal on an electric.
My system has a check valve and a blowdown valve, it's difficult to really tell exactly what people are talking about when you don't know how their systems operate ( this is not at all directed at you
@jjvw ).
Just add a small section of hard line somewhere, it is an extremely easy way to add a small tank. I used to have a copper line running down to a compressor drain valve and that was plenty. When I redid my system recently I just used a chunk of 6061 for a manifold and drilled it out so I have a little more reserve there.
