I wouldn't recommend the VC or Hagrid SRL to TPR readers. If you truly don't care where you sit and can get in the SRL right when it opens/reopens for VC, sure go for it. You still don't have a great idea of how many people are waiting beyond the locker room and could get end up waiting just as long as the regular queue.
Hagrid's SRL seems to be uncapped lately. Like, extending out of the building down the stairs almost to the first section of ramps beyond the main archway entry. Have all the Hagrid SRL as you want
Operators are very vocal about how the SRL: has no estimated wait time. you will not have any seat preference. you will not sit with someone else you got in line with. Sadly most guests think it's an express-like hack they learned from socials.
Meanwhile since Spring Break/East crowds, I've experienced VC many times with a 20-40 minute via the regular queue as well as Hagrid 45-60 minutes (even on the weekends).
I do recco SRL for Forbidden Journey, MiB, Transformers, SpiderMan, River Adventure, and Hulk.
