First, thisthis looks like the post on Meta Stack Overflow announcing the nuking of "too localised". Before I get into the desirability of another close reason, it would make sense to see if the "replacements" work well with what we want.
Judging from that article, the intention was to use the "off-topic" reasons instead of "too localised"
Given that the "missing context" reason:
This question is missing context or other details: Please improve the question by providing additional context, which ideally includes your thoughts on the problem and any attempts you have made to solve it. This information helps others identify where you have difficulties and helps them write answers appropriate to your experience level.
is the only one with any sort of site-specific text, it sounds like we either need another off-topic reason or to break this one down (or possibly both). At least in my opinion, we really ought to have more reasons, each one with a narrower scope (i.e. no "umbrella" close reasons). A close reason with a wide scope lends itself to misuse. For comparison, Stack Overflow has 5 reasons with site-specific text.
TL;DR I agree that we should have another close reason, and I think the list of "off-topic" close reasons should at least be looked over again while this is being discussed. Also, if possible, we should avoid having "umbrella" close reasons; even if this means creating not one new reason, but two or three.
