It all depends on what level of effort you're willing to make:

- if you really want to just use and not participate at all (i.e. report
  issues, test pre-releases etc), 5.10 will be more suited.

- if you're willing to participate, you can start to encourage others to
  do so as well in order to convince Greg that he will not be alone in
  this tedious task and that it's worth extending 5.15.

- or if you're willing to invest a little bit of time but don't want to
  engage too far, you could also take the risk of going for 5.15, hoping
  that it will be extended, knowing that if it's not, it will be your
  job to deal with backports (which usually is a real pain and would
  justify giving back some help on official support instead).

That's just numbering, and should in no way affect maintenance of existing
code.

Hoping this helps,
