I don't think that's remotely a starter. Asking people to install an old and possibly buggy version of a perl module is not something we should do.
I think the barrier for this is pretty high. I try to keep module requirements for the buildfarm client pretty minimal, and this could affect a much larger group of people.
Those are good reasons.
For those who already responded, are your concerns limited to the dependency issue? Would you have concerns about a templating library that was developed by us and included in-tree? I'm not suggesting suggesting we write one at this time, at least not until after we make a here-doc-ing pass first, but I want to understand the concerns before embarking on any refactoring.
