This kind of design rationale is potentially useful to include inline
as a block comment. The kinds of questions reviewers have are often
going to be the same kinds of questions future maintainers have, and
"why" data regarding core architectural decisions is less likely to go
out of date as future maintainers make changes.

Aye, a definite +1 for "better" over "perfect".
