I spoke about this matter with many colleagues, and still was not able to find an agreed solution.
Our flight operation manager tends to apply the more restrictive interpretation, using the planning minima even after lift off, at least when it comes to destination airports.
Let's make an example, which actually occurred to me recently.
Destination was Cannes, and in order to comply with the planning minima a headwind of at least 10 knots was required in order to land rwy 17.
The wind required was present in the forecast, and two alternates were selected. All the dispatch requirements were met.
During the descent to destination we checked the wind, which had decreased, falling below the minimum component necessary for us in the planning phase.
What were we supposed to do? It is actual phase now, and WITHOUT the 60% factorization we are able to take any runway, but WITH the factorization we shouldn't be landing.
