I think this sort of pawn stance with a splash of colour thrown over it is very common. And is what a typical D&D module/AP encourages.In my recent game...
Underdark bugbear ranger decides to abandon the Underdark, the only home he has known, to the demon threat (OotA), abandon his personal quest of vengeance vs an Illithid that he had been a thrall for many years, to join a surface party he had known for a day to deal with their issues.
Now I can make it work in the fiction, but there was NO attempt made by this player. The idea never crossed his mind. This dude is an old player who has just joined our table after many years. He is in need of desperate retraining IMO.
Because as soon as the player tries to introduce anything more substantive, they will start bumping into the limits of the module/AP.
The "social contract" stuff in the current version of the game also encourages it:
You must provide reasonably appealing reasons for characters to undertake the adventures you prepare. In exchange, the players should go along with those hooks. It’s OK for your players to give you some pushback on why their characters should want to do what you’re asking them to do, but it’s not OK for them to invalidate the hard work you’ve done preparing the adventure by willfully going in a different direction.
If you feel like you’re keeping up your end of the bargain but your players aren’t, have a conversation with them away from the gaming table. Try to understand what hooks would motivate their characters, and make sure the players understand the work you put into preparing adventures for them.

If the work that the GM has done is preparing an adventure/module/AP, then this social contract is a clear recipe for pawn stance, or pretty thin/"mere colour" author stance. It doesn't encourage genuine inhabitation of the character at all.
This is not a criticism: I've done, and GMed, my fair share of pawn stance D&D. But for a RPGer who is looking for a bit more or a bit diffrent, then as you said, some "retraining" may be necessary.
