First they are two side characters so they are going to appear less plus they both have a lot in common personality wise unlike Naruhina.
What does being side characters have to do with them not developing properly? Shikamaru is more of an MC than Sakura is anyways. And Hinata is a minor too.
They are an organic pairing we see develop on screen as opposed to accepting the girl already likes the guy from the beggining and everything is based off of that. Pairings that involve one side crushed with minimal interactions that only happen at the end so the one obsessed side can be happy is not my cup of tea.
Minimal interaction? lmao

It is implied that Shikamaru and Temari spent lot of time together helped the partnership with their villages as well as the chuunin exams which is more than Naruto and Hinata are implies to have got.
Doesn't mean romance or interaction between the two. Meanwhile, it it out right said Hinata and Naruto bonded in the 2 years during the last.
I know you hate Hina, but use logic please.
