By ‘moot’ I mean ‘a matter for discussion or debate’. I did not say ‘questionable’ as that would imply an opinion I do not necessarily hold.
(I spotted the difference. If you went into LUX (class D) on an IFR clearance you would be guaranteed separation from other IFR traffic, whereas on a VFR clearance you would not, so the amount of ‘see and avoid’ needed is a function of the ratio of VFR to IFR in the zone).
