Most writers these days unless they or the editors are fans of the character, won't try or know the character can do much beyond what the notes and then there are those that when using the character won't let the character use their versatility because they need the story to go a certain way.
It is why Blackbolt's powers fluctuate from enhance physical strength on par with the Thing, a sonic scream went from something that whisper would level a city block and electron control to just a high powered sonic blast and strength in many of his guest appearances. It is why Wolverine can sometimes swim just fine despite having adamantium bones that should weigh him down. Or various other instances where a character's powers act outside of previously established limits or a character doesn't use it for such. These days some writers don't want to explain anything because it will throw off the story they have set up or just didn't do the research.
