This should be already addressed by changes from #73590 with somewhat different approach.

Hum... I think both approaches are actually completing each other. I'll fix the format issue.

This patch seems wrong. When bootstrap is passed a filename, we expect that said file exists (and is valid TOML); we should not ignore errors. I believe it can be closed, but I'll leave that to @GuillaumeGomez's discretion.
