PIP 0028 and JSON and JSON parsing can all be considered bad for security and therefore this pip can also be dismissed as MUCH unwanted feature of any pascal coin software or related software.
It is better to communicate via binary/byte based and structured formats, these are somewhat easier to secure then parsers which are hard to understand for most computer programmers and are basically inexact science.
At least logic/bits/bytes/math is somewhat more exact science is better understood and should therefore be easier to secure.
Relieing to much on JSON and parsing technologies will DOOM pascalcoin to the lend of SCAM coins and EXCHANGE hacks so is my believe ! ;)
(Therefore PIP 28 is to be avoided)
