If by “function” you mean encoding protein production that might be true but some of these non protein coding parts of the genome produce a form of RNA called “micro RNA”.

As time goes on more functions for this noncoding dna are being found.

Indeed, it looks like this noncoding regulatory DNA; in addition to the other regulatory DNA already known about - might make up as much of the genome as the actual genes themselves!

Still no known function for the majority of the genome.

Not saying one won't be found, but a hypothesis of “junk” that might be beneficial to be kept around, and might be of use some day - is still a reasonable hypothesis. One which is strengthened by findings like the envelope protein of an ERV being used by placental mammals - not weakened by it.
