Right, that is one option.

A thing that could be done, without mandating either LOT=3Dtrue or LOT=3Dfa= lse, would be to have a release that requires a `taprootlot=3D1` or `taproo= tlot=3D0` and refuses to start if the parameter is not set.

This assures everyone that neither choice is being forced on users, and ins= tead what is being forced on users, is for users to make that choice themse= lves.
