As far as I understand the issue is a performance one.

For example, scheme is hard to compile towards the JVM or standard C because both lack proper tail call implementation (poping the parameters in the stack before calling a function in tail position).

You can of course circumvent this because as you say the target language is Turing complete, but you lose a lot on performance if the target isn't tailored to this particular use.
