Due to the TWY - GS antenna configuration the same was an issue at SVO for 25L (it's been a while).
Their ATC solution was to declare NDB apch in progress in VMC+ conditions, when the close holding points were needed to keep high flow. .
Not saying better or worse, just in agreement with w. that it is a major issue.
Somewhat related: Approaching LGW behind an A380, the controller would offer an RNAV approach with the standard super-separstion, or an ILS which required (almost) additional 2 NM in trail.
Maybe someone here kept the ILS scales on during the RNAV APCH and observed what was the actual behaviour?
