2 things:
- I think we should pick 1.53 if possible, since that's what mozilla use
  for their esr91 binaries
- I don't think we need to rename the packages unless there's evidence
  of breakage that can't be easily fixed by either simple patches or
  removing the affected packages.  Renamed packages are acceptable but
  that seems like extra work and overhead that may not be necessary.
