Not saying it’s used every day or every month. The point is it CAN be done. You say you don’t know of anyone that has used it, so be it but it can be used, it’s not experimental. The long term outlook is the same as any other form of external beam radiation. Just another tool to put in the tool box if you need it.

Search of the web says it’s in trial. I have a suspicion that it is not been used by a lot of people since I’ve never heard of anybody having it. When they start doing something like that, they evaluate how well it’s working for quite a long time since it takes many years for the side effects to occur.
Yes, researchers are actively studying the use of proton beam re-irradiation (sometimes called salvage proton therapy) for patients who have experienced a recurrence of prostate cancer after receiving a "lifetime" dose of prior radiation therapy (such as external beam radiation therapy, or EBRT).This approach is considered a promising option for treating local recurrences while minimizing damage to healthy tissues that were already exposed to radiation.
Here’s a couple of articles about it.

There’s a lot more information about the studies, but the recommendation is for specific, up-to-date trials, it is recommended to search on ClinicalTrials.gov using keywords such as "prostate cancer," "re-irradiation," and "proton."
