[dev-context] Spacebefore and spaceafter in strc-mat

Hi,

strc-mat sets:

\def\beforedisplayspace
   {\doifnot{\formulaparameter\c!spacebefore}\v!none{\blank[\formulaparameter\c!spacebefore]}}

\def\afterdisplayspace
   {\doifnot{\formulaparameter\c!spaceafter}\v!none{\blank[\formulaparameter\c!spaceafter ]}}

Other environments that provide spacebefore and spaceafter keys 
(delimiters, floats), do not check if the key is none.

I don't really understand why this check is done. Can we delete this 
check?

Aditya
