So instead the character gets inserted into other works like happened with Kamala being written into Amazing Spider-Man only to then get killed off so the X-Men could bring her back as a mutant.

The amount is of downright stupidity involved in all that is still to this day staggering.

First off none of the ASM cast had any chemistry with Kamala, and their attempts at mourning her were just shit flashbacks that were made up in the issue so there was no gravitas to any of it.

Second, her death wasn't even done very well or somewhere it would make even the slightest bit of sense. Throwing her into ASM was never well received, not that ASM was for the longest time then either, but most people probably missed it because of where and when it happened.

Third, she was barely dead for a month and Emma Frost mind wiped most people so they never knew it happened.

Fourth, her mutant powers turned out to be exactly like the live action version of the character to the surprise of nobody. The whole thing was done for MCU synergy.

The later issues where she comes back are just as stupid for a whole list of other reasons, like trying to do the vitiligo meme but then drawing someone who might have had alopecia instead because apparently the writers and artists are just that fucking stupid.
