   I think this might be premature. See 
https://go-review.googlesource.com/c/go/+/462355 
   
   > The arena goexperiment contains code used inside Google in very
   limited use cases that we will maintain, but the discussion on 
[#51317](https://go.dev/issue/51317)
   identified serious problems with the very idea of adding arenas to the
   standard library. In particular the concept tends to infect many other
   APIs in the name of efficiency, a bit like sync.Pool except more
   publicly visible.

   > It is unclear when, if ever, we will pick up the idea and try to push
   it forward into a public API, but it's not going to happen any time
   soon, and we don't want users to start depending on it: it's a true
   experiment and may be changed or deleted without warning.
   
   This isn't to say it's a terrible idea of course - just to be very cautious 
about depending on it.
