"The reader finds themselves wondering, "does send_data handle an empty array correctly?", and squanders precious seconds scrolling down the page to look. Despite the relief at discovering that of course it does, those seconds--entire, complete, juicy seconds in which the reader might instead be sucking out all the marrow of life, as Mr. Thoreau would no doubt have said when faced with a similar situation--could, at the programmer's discretion, be saved by guarding this call with a kind, if strictly unnecessary, unless."

This is a bit of history and a bit of a quirk in timing...

The history first...

Vagrant has all manner of provisioners effectively supporting any CM tool as well as supporting plugins to add more. When I started on Packer, I basically copied this model (nit: provisioners aren't pluggable anymore cause no one ever used that functionality but the interfaces are very similar and Packer also supports all manner of CM tool).

know how much roadmap-project work people can do in a week. commonly it's 40-60% of their time. call that PR (for Project Ratio).
make a spreadsheet: [Story, Description, People, Weeks, Person-Weeks].
break the work down into comprehensible pieces, where you feel confident saying things like "this will take 2 people, working full-time, 3 weeks to implement." in particular, break down milestones that deliver value; where, if the business told you to do something else, that would be okay, and the work done wasn't wasted.
fill in your spreadsheet columns appropriately (say 2 people, 3 weeks, 6 Person-Weeks).
sum up the Person-Weeks. ("People" and "Weeks" are for later.)
