I don't think I'll object. At some point the best testing is "lots of users".

TLB issues are a bitch to debug, but at the same time this is clearly
a "..but at some point we need to bite the bullet" case. I doubt the

But yes, please do give it as much testing as humanly possible even
without the wider coverage by random people.
