When adding an Opamp to a circuit, you'll get a TL081:
That's not a sane default. A sane default for most questions, that wind around "theoretical" opamps would be "no type"; anything else will just imply specs that (hopefully) aren't the ones of the actually used device.
This leads to avoidable confusion, especially with beginners; for example, "why is my opamp-based PD controller unstable" is quite different from "why is my TL081-based PD controller unstable".
Thus, let's remove that default value; having that default helps noone (aside from these marginally few who are actually using a TL081, which is pretty much an obsolete part from 1977).
