On the other hand, it may take that engineer less time to create a page-specific endpoint than it would be to create something more generic that might serve other purposes (that may never come to pass), which may also involve talking to other teams, checking what future plans are, etc.

And that's assuming it's a new endpoint; if there's an existing endpoint that does almost what's necessary, they may need to check in with that team about what modifications to the endpoint would be acceptable, etc.

Single-page endpoints aren't great, but often times they're acceptable because they end up being a half-day task instead of a week-long slog.
