I would say that rather than deleting the line, it would make sense to leave it in but more restricted. What if we permitted Cryer ID'd pilots to engage Outcasts within Sigma-17 and -19 (Since Sigma-19 is probably their main thoroughfare into -17), and to engage Golden Chrysanthemums and Lane Hackers in Galileo and Kepler? Those aren't part of Liberty, strictly speaking, but could reasonably be considered part of their ZoI.
A way a lone a last a loved a long the riverrun, past Eve and Adam's, from swerve of shore to bend of bay,
brings us by a commodius vicus of recirculation back to Howth Castle and Environs.
