I do it every day mate. I stabilize lume all the time on vintage watches, and I fully warranty my work. This isn't some risky rare procedure that only a few people do - watchmakers all over the world do this every single day. Service centers just choose not to do this simple procedure, so they just replace the hands or dial.
You may believe that what Rolex chooses is all fair and good practice, and if you feel that way, it matters not to me really. You do whatever you wish with your watches - you can smash them with a hammer if you like. But let's not pretend that Rolex is acting in the customer's best interests here, because they are certainly not.
Service centers take short cuts all the time for the sake of saving a few minutes here or a few minutes there. This is why they replace entire mainspring barrels instead of just the spring, and for the most part waste the barrel drum, barrel cover, and barrel arbor. This is why instead of bushing a worn hole in a plate, the replace the entire plate. Burnishing rough pivots - nope they just replace the wheel. Watchmakers who work in service centers have hard won skills that they are not really allowed to use, because the brand policies turn them into parts replacers.
Rolex certainly has the right to service the watches however they want to, which is why people who are considering sending a watch there need to understand that Rolex is looking after their own interests, not the interests of the watch owner. If you want to argue that people shouldn't be informed of what may happen to their valuable vintage watch when they send it to the brand, well we will disagree on that stance until the end of time...
