Unexpectedly, I find myself in agreement with you. I think we should<br class="">
ditch INST_CONDA=0, now that yt is able to be installed in a multitude<br class="">
of ways, and now that the dependency stack is also much easier to<br class="">
install.<br class="">
<br class="">
This will also lighten the burden of maintenance that we put on<br class="">
ourselves when we add optional or explicit dependencies.<br class="">
