It depends on how you do it.
Many tanks in series, narrow tubing, restricted brasstubing (many suppliers have their tubing cut so the ends are in less diameter).
Tanks made of the same layup as smaller tanks are much weaker but can easily be reinforced my a belt of carbonrowings.

Going thru the factors that is the cause, very often makes it NOT a problem, yes.
