Your point about men having a different rule assumes inheritance dynamics are similar from a father as from a mother. Clearly, an assumption is made that when fathers hand assets down in relatively conservative, religious, patriarchal societies, that emphasis will be placed on preservation of inheritance within a local network. Now that's an assumption - fair enough - but it's grounded in realities of experience within patriarchal societies, which apply in many parts of the world, not just Muslim dominant areas. The aim is ostensibly to preserve local networks of assets following inheritance.
If - as you suggest - absolute equality of genders was the motivator for the abrogation, all Delhi had to do was modify the article to suit the UN Charter and Modi's personal concerns for Kashmiri females. Nobody would have minded.
Clearly however, this is a red herring.
Regarding Constituent Assembly, read the second article I posted, which explains the issue very well.
The absence of a CA was actually a problem for Modi because he couldn't move without an in principle agreement from a CA, hence this was one very important element of 370 that he had to rewrite.
Again - no loopholes here, just shameless rewriting.
