We have `guarantee` which will catch the bug. However ASLR might make difficult to reproduce the bug.
I think it is not critical for 8 and 11. We are working to make JVM performance with 240M CodeCache similar to the performance with smaller CodeCache. This will decrease chances that people will use small CodeCache. We will be backporting enhancement to 17. 
It looks to me, risks are mitigated in old releases. There is no need for backports.
