You don't have to fear anything, if it works with BIG-REQUESTS then it just works (mostly).
This is just that, as Uli said, the BIG_REQUEST extension support is very buggy in NX and thus, some apps work with it (or even need it to work such as VLC or your 3D viewer) and some don't (such as ATOM.io, VSCode and many other elektron based applications).

By now, depending on your needs, you should enable it or not.

Hi Uli, 

ok, when I put 

X2GO_NXAGENT_DEFAULT_OPTIONS+=" +extension BIG-REQUESTS" 

into /etc/x2go/x2goagent.options then paraview starts without errors. 

But the comment says: 
"Disable BIG-REQUESTS, nx-libs does not implement this extension 
correctly. Leads to all sorts of weird crashes if left enabled." 
Is this still true? Do I have to fear all sorts of weird crashes?
