I feel that the stupid nit writers (which I will refer to them as when they make some blooper IMNSHO!) thought Willie was unworthy of Maggie so they'd pair her up with someone other than Willie
It can certainly be frustrating for fans of certain characters when the writers don't see them in quite the same way as their fans might. However, it's actually the writers who've conceived the characters who know them best and who have designed specific places/purposes for them within the canvases of the stories they're telling. It doesn't make the writers stupid when they don't use a character in a way that his/her fans might like to see.
How any specific character is interacted is completely within the purview of the writers.
(The only quibble I normally have is when a character has been presented one way within the various stories and then he/she might suddenly behave in a completely different way with no explanation of why/how said character's behavior would have changed.
