Saw this today and have a ton of thoughts on this topic
I worked at a destination amusement park (Cedar Point) in guest services two years ago and did a DCP last year (albeit in concierge at a resorts). The amount of abuse I saw of the system at the amusement park I worked at was staggering, and at WDW, I witnessed many cast members and people around me at the parks when I went that I knew who abused the system as well.
In my opinion, this change is really fantastic. I completely understand that it will be a very unfortunate extra hassle for those who actually need the program, but if it even weeds out half of the people who were abusing the system, I see this as a massive win. I was very angry watching so many people abuse the system at both parks/resorts I worked at, and I really want what's beneficial to all guests and this is it. I can tell you first hand from going to the parks and talking with attractions CMs, that DAS currently accounts for most of the Lightning Lane lines, so if you've seen long LL lines that put the standby line to a halt, this is why.
I know I may have a bit of a hot take on this whole thing, but I'm currently going to school for resort and attraction management, so this is something that I personally have thought about and taken a look at these last few years. I think WDW is making a move in the right direction here.
