Because the 'servers' in existence speak only one language and it is that problematic one we want and need to get rid of. Your 'transpile' handwaving won't fly. You are blindly presuming that the 'SQL equivalent' (a) always exists (it doesn't) and (b) can always be generated by an automated transpiler (it can't).
