The odds of system management scripts I wrote a decade ago and haven't touched since living in a virtualenv is approximately zero. The issue with switching where /usr/bin/python points to python3 is to avoid problems on systems. I don't think virtualenv is relevant. In any case, if you're using virtualenv, then you're enough of a Pythonista to be expected to know how it works. That doesn't particularly bother me.
