IMO that would be a mistake because Simplified Technical English cannot properly represent business domains specifically when talking about using specific concepts from those domains. It can explain those concepts but I think it will fail short or naming them.

So I think making that default as it is will create bugs. I ran an experiment here https://allaboutcoding.ghinda.com/explain-to-me-in-simple-te... (of course it is fit to my usage) see section "What about understanding and facts" and ASD-STE100 fails, in my experiment, to return facts as I have defined them in those cases compared with no instruction or just saying "use Simple Technical English".
