Sure, but there is a middle ground between making something forced and instructing to give some sort of recognition during the flight.

It would not fit the style of this airline to make it a sort of computerised check-box "this is what must happen" setting. But you could give a little bit of structure if you'd instruct crew to do something rather than stating what exactly. And then with a list of common ideas ranging from leaving a card at the seat, welcoming in person, offering a drink from J, giving a free WiFi code (ok, not relevant anymore) or similar.

It's just weird if the person next to you is offered a drink from J and explicitly being thanked for being a loyal customer and you're sitting there as a PfL and they don't even say hi... Last year I thought they'd implemented something as from January I had consistent recognition of status during each flight. Was a clear night and day difference: first choice for meals, asking for the list of missing houses at the beginning of the flight so they could already find the ones during a quiet moment, bit of small talk about experience on recent flights. But after two months or so that disappeared as suddenly as it was there.
