Command line argument "--install-tests" is passed to R CMD INSTALL by default

Is it intentional in devtools::install()? The only way to ignore "--install-tests" is to set keep_source = TRUE. Thanks.

    opts <- c(
      if (keep_source) "--with-keep.source",
      "--install-tests"
    )
    if (quick) {
      opts <- c(opts, "--no-docs", "--no-multiarch", "--no-demo")
    }
    opts <- c(opts, args)

It's been this way for a very long time and I can't find any related issues or discussion. So I'm going to say, yes, this is intentional and has stood the test of time.
