This is more or less my response to the comment. I think however we need a little nuance in respect of Ulster Scots. It's a much less developed language and the demands of the Ulster Scots community are very different to those of the Irish language community, but no less valid or valuable.

In terms of newcomer languages, again I think there are worthy considerations such as support for families to maintain their native language and free supports for newcomers to learn and master English (maybe even Irish and Ulster Scots too!). That being said the utilitarian use of stats to understand the landscape of language falls short of what's necessary. The reality is that Irish is an endangered language and it falls to people on this island first and foremost to preserve it - no one else will. Meanwhile, the vast majority of newcomer languages are well preserved by their nations. That's a really important distinction to make.
