Should system prep verification use pkgbuild::check_build_tools()?

[batpigandme]

Currently the verify-system-prep section suggests using devtools::has_devel() to verify system readiness for development:

The usethis setup vignette says:

• pkgbuild::check_build_tools() is the most current function. It can be installed via install.packages("pkgbuild").
• devtools::has_devel() was a function in devtools, at least up to v1.13.5, so you might still see references to that. All functionality related to package building now lives in pkgbuild. But once you have installed pkgbuild, you should just use the function pkgbuild::check_build_tools() instead.

Is it too soon to move to pkgbuild::check_build_tools() for the What They Forgot text? (If not, I'm happy to submit a PR).

I filed an issue for pkgbuild here re. possibility of returning something to signal success, but I'm thinking it might be better-suited as an usethis feature request…
