No, not since the FAI unilaterally reneged, after 50 years of happy operation, on the Gentlemens' Agreement* with the IFA, whereby both Associations pledged not to pick players from the "others" jurisdiction.
Which is not the same as saying I wouldn't be pleased on a personal basis for the Republic's fans, who seem to me to be amongst the best on the international scene.
This btw is somewhat different from an earlier World Cup experience in Italia 90. I went out to watch that tournament along with two Scottish mates, becoming an "unofficial" member of the Tartan Army along the way.
Then when the Jocks exited the tournament predictably early(!), I decided to stay on when they went back home.
Being a Spurs fan living in London, I might have followed England from this stage (I went to Bologna for their game with Belgium), but tbh there was so much hassle with hooliganism etc, that I had no appetite for it.
Meanwhile, I was very struck by a minor incident where I saw two guys from NI who just happened to be in my hotel, go up to a group of ROI fans and congratulate them on qualifying for the 2nd Phase.
After that small act of sportsmanship, I decided to tag along with the ROI fans, having a whale of a time in the process. Indeed, I actually got to attend the Romania game in Genoa, which was a mighty occasion, before my funds finally ran out and I had to return home.
So it's nothing personal (you bunch of cnuts!

)
* - An Agreement which ironically was requested by the
FAI
