I'd hazard to guess that Milankovitch cycles come up seldom because they're pretty widely recognized as not being a determining factor in the climate change we see. For an in-depth explanation of how the phenomenon relates to climate change see this well-sourced video: https://youtu.be/zQ3PzYU1N7A
They are relevant. Most of the previous interglacials during this ice age were about 10ka. How come this one continues and how long do we expect it to last? To know this one uses Milankovitch cycles.
There is quite some debate over the issue, but we probably have 5-30ka left of warm weather.
