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="">
