That would imply that quad_qagi would be faster without compiling than
with.  I think it was done that way on the assumption that the
integrand would be called many times to perform the integration, so
the function is compiled.  If that's not really necessary, why not
just remove the compilation completely?

I think I measured runtime with and without compiling, and compiling
was faster.  But perhaps that was true for my tests but not in
general.
