Dusklight Razorwing - Are the eggs still gated?

I’m interested in getting the Dusklight Razorwing but everything I’ve read from the 9.1 era is that after the first egg of the day, they dramatically reduce the droprate.

Do I still need to spend 6 days in Korthia, or can I grind it out in a few hours?

If I remember correctly, the drop reduced slightly until you had 3, after that it was better to just come back the next day. That was then.
