What it means is that when one starts to write a software which is 
expected to be connected to the rest of the world, one has to ask how 
good this connection is to happen.
In the case of MathML-content, I thought the lack of specification of, 
at least to my knowledge, the inverse-trigonometric functions have made 
Mathematica and Maple MathML-content behave inconsistently.
Based on this experience (which I'd like to see one day written 
somewhere under an "interoperability" heading in the w3c.org/math 
pages), a new software being written should then declare something like:
the inversed trigonometric functions shall behave the same as Maple, 
Mathematica (or OpenMath) ones.

Hence my statement which was, sorry for that, sort of sketchy.
I would surely not prevent new software to be written!
