Originally, the PGO data was a bunch of proprietary blobs which I could not legally redistribute. When switching to Firefox binaries, I wanted to keep things as similar as possible, to keep the repo download size down, and not waste disk space. But in this year, megabytes are cheap, everything else is huge, I doubt many people said no, asking the user is an extra step, and buildbots are often sandboxed and can't download them. Let's just cut out the middlemen.
