The '66 namings were of their time, the choice of dead leaders everyone could get behind, papering over the cracks of the Civil War. I doubt we'll see further Rising/WOI namings on a large scale.
Interesting to note the names that stuck in regular use (Kent, Heuston, Colbert) with the rarely used (O'Hanrahan, Casement, MacBride)
Trends these days are naming things after people in the usual sports, literary and arts fields. But also formerly ignored Irish people in ww2 (helping Allied side obvs!), social issues, peace process, and much more of an emphasis on women.
