If you can't understand why this has not received press coverage earlier it's because there was a period of time where there was a media black out on the case in Ireland and because minimising press coverage is part of the strategy for getting self ID laws passed by stealth.
Here is a quote from an article in the law gazette:
"Campaigns to change the law to allow children to change their legal gender should 'avoid excessive press coverage and exposure' according to an international survey singling out the UK for criticism."
Here is the full article, it's short but contained within it is some of the highlights from the infamous Dentons Report.

Here is a link to the full Denton's Report. Although it talks about trans youth the tactics it describes have been deployed to push through adult self ID laws. You need to click "download full report".

Here's what Denton says about Ireland, page 55.
The most important lesson from the Irish experience is arguably that trans advocates can possibly be much more strategic by trying to pass legislation “under the radar” by latching trans rights legislation onto more popular legal reforms (e.g. marriage equality), rather taking more combative, public facing, approaches. Another lesson is that compromise is a double-edged sword. Compromise on legal gender recognition for young trans persons was critical to getting the legislation passed in Ireland, but it might take years to revise the legislation to render it more favourable to trans youth.
Never doubt they are playing the long game.
