Why not support Special Judge & Memory Limit
This is not a bug, but an enhancement.
Maybe users could choose local SPJ program and judge there solution with the SPJ.
Also, the memory limit is important in some problems, so I think it is a better choice to support it.
I agree with you.
Supporting Memory Limit is difficult across platforms because detecting memory usage requires accessing system API. But the extension environment, which is NodeJS, does not support these things.
I found the same problem with SPJ, so I wrote a new extension to solve it! You can try my CPH-NG (Marketplace, GitHub)! It can load SPJ program using testlib and raw executable files!
